SparkToro and Followerwonk joint Twitter evaluation

TL;DR – From Might 13-15, 2022, SparkToro and Followerwonk performed a rigorous, joint evaluation of 44,058 public Twitter accounts lively within the final 90 days. These accounts had been randomly chosen, by machine, from a set of 130+ million public, lively profiles.
Our evaluation discovered that 19.42%, practically 4 occasions Twitter’s This autumn 2021 estimate, match a conservative definition of faux or spam accounts (i.e. our evaluation seemingly undercounts). Particulars and methodology are supplied within the full report under.
For the previous three years, SparkToro has operated a free software for Twitter profiles known as Faux Followers. Over the past month, quite a few media retailers and different curious events have used the software to research would-be-Twitter-buyer, Elon Musk’s, followers. On Friday, Mr. Musk tweeted that his acquisition of Twitter was “on maintain” because of questions on what % of Twitter’s customers are spam or pretend accounts.
SparkToro is a tiny crew of simply three, and Faux Followers is meant for casual, free analysis (our precise enterprise is viewers analysis software program). Nevertheless, in gentle of serious public curiosity, we joined forces with Twitter analysis software, Followerwonk (whose proprietor, Marc Mims, is a longtime buddy) to conduct a rigorous evaluation answering:
- What’s a spam or pretend Twitter account?
- What % of lively Twitter accounts are spam or pretend?
- What % of Mr. Musk’s followers are spam, pretend, or inactive?
- Why ought to our methodology be trusted?
We deal with every of those questions under.
What’s a Spam or Faux Twitter Account?
Our definition (which can differ from Twitter’s personal) can finest be described as follows:
“Spam or Faux Twitter accounts are these that don’t usually have a human being personally composing the content material of their tweets, consuming the exercise on their timeline, or partaking within the Twitter ecosystem.”
Many “pretend” accounts underneath this definition are neither nefarious nor problematic. For instance, fairly a couple of customers discover worth in following a bot like @newsycombinator (which routinely shares frontpage posts from the Hacker Information web site) or @_restaurant_bot (which tweets images and hyperlinks from random eating places found by way of Google Maps). These accounts, arguably, make Twitter a greater place. They simply don’t have a human being behind a tool, personally partaking with the Twitter ecosystem.
Against this, most “spam” accounts are an undesirable nuisance. Their actions vary from peddling propaganda and disinformation to these trying to promote merchandise, induce web site clicks, push phishing makes an attempt or malware, manipulate shares or cryptocurrencies, and (maybe worst) harass or intimidate customers of the platform.
SparkToro’s Faux Followers methodology (described intimately under) makes an attempt to determine all of most of these inauthentic customers.
Our programs don’t, nevertheless, try to determine Twitter accounts that could be irregularly operated by a human however have some automated behaviors (e.g. an organization account with a number of customers, like our personal @SparkToro, or a group account run by a single individual, like Aleyda Solis’ @CrawlingMondays). We can’t understand how Twitter (or Mr. Musk) may select to categorise these accounts, however we bias to a comparatively conservative interpretation of “Spam/Faux.”
What % of Energetic Twitter Accounts are Spam or Faux?
To get essentially the most complete doable reply, we utilized a single spam/pretend account evaluation course of (described under) throughout 5 distinctive datasets.

The datasets represented above are:
- Followerwonk Random Pattern (44,058 accounts) – Followerwonk presently has 1.047 Billion Twitter profiles listed, up to date in a steady cycle that takes ~30 days. Any account that has been deleted (by the consumer or Twitter) will get eliminated and isn’t included within the depend. Of these, 130 Million are “lately lively” by Followerwonk’s definition, i.e. they’ve despatched tweets throughout the previous 9 weeks, and are public, not “protected” (Twitter’s terminology for personal accounts).
Marc wrote code to randomly choose public accounts from Followerwonk’s lively database, and handed them to SparkToro for evaluation. Casey on our crew additional scrubbed this checklist and ran 44,058 public, lively accounts by way of our Faux Followers spam evaluation course of, discovering 8,555 to have an overlap of options extremely correlated with pretend/spam accounts. We imagine this dataset represents one of the best, single reply to the query of what number of lively Twitter customers are more likely to be spam or pretend.
- Aggregated Common of the Faux Followers Device (~500K profiles run, 1B+ accounts analyzed) – Over the past 3.5 years of operation, SparkToro’s Faux Followers software has been run on 501,532 distinctive accounts, and analyzed hundreds of followers for every of these, totaling greater than 1 billion profiles (although these usually are not essentially distinctive, and we don’t hold monitor of which profiles had been analyzed as a part of that course of).
This represents the biggest set of accounts on Twitter we may purchase, but it surely contains evaluation of many older accounts that haven’t despatched tweets within the final 90 days and thus, seemingly don’t match Twitter’s definition of mDAUs (monetizable Each day Energetic Customers). We’ve included it for comparability, and to point out that an evaluation that features merely random Twitter accounts (vs. these which were lately lively) might not be as correct.
- All Followers of @ElonMusk on Twitter (93.4M accounts) – Given the distinctive curiosity in Mr. Musk’s account, and the central function it performed in triggering this report, we felt it sensible to incorporate an entire evaluation of the practically hundred million accounts that observe @ElonMusk. This dataset contains older profiles that haven’t tweeted within the final 90 days (and don’t match Twitter’s mDAUs definition).
- Energetic Followers of @ElonMusk on Twitter (26.8M accounts) – A extra honest evaluation of Mr. Musk’s Twitter following would solely embrace accounts which have tweeted up to now 90 days. With a view to match the methodology utilized in our Followerwonk evaluation, we chosen solely these 26,878,729 matching this standards and have damaged them out within the chart above.
- Random Pattern of 100 Customers Following the @Twitter account (100 accounts) – In a follow-up to his tweet on Friday, Might thirteenth, Mr. Musk stated that “my crew will do a random pattern of 100 followers of @twitter; I invite others to repeat the identical course of and see what they uncover.”
Whereas we don’t imagine this course of to be a rigorous, statistically important pattern set, we’ve however included it for comparability functions. On Saturday, Might 14th, we manually took a random pattern of accounts from the general public web page of @Twitter’s followers right here. With a view to get the least biased pattern, we included solely public accounts, solely those who despatched tweets up to now 90 days (after Feb twelfth, 2022), and solely accounts created earlier than Might, 2021, i.e. they’ve been on Twitter 1+ years (many current accounts, particularly in gentle of Mr. Musk’s actions, may bias the pattern).
- Twitter’s Most Latest Earnings Report Estimate (Unknown variety of accounts) – Twitter’s public earnings report, quoted by Mr. Musk in his current tweet, shares that <5% of mDAUs (monetizable Each day Energetic Customers, outlined of their 2019 report right here) are pretend or spam. We’ve included this estimate within the chart for comparability, and famous that the methodology is undisclosed.
Undoubtedly, different estimates shall be made by different researchers, hopefully with equally giant and rigorous datasets. Given the restrictions of publicly obtainable information from Twitter, we imagine essentially the most correct estimate to be: 19.42% of public accounts that despatched a tweet up to now 90 days are pretend or spam.
What % of Elon Musk’s Twitter Followers are Spam, Faux, or Inactive?
In October of 2018, SparkToro analyzed all 54,788,369 of then US President, Donald Trump’s, followers on Twitter. We replicated that course of for this report, analyzing all of Elon Musk’s profile’s 93,452,093 followers (as of Might 14, 2022).
When operating a Faux Followers report by way of our public software, we analyze a pattern (a number of thousand) of a Twitter consumer’s followers. When an account has a really giant variety of followers, this technique can deviate from what a full evaluation of each follower exhibits. Over Saturday, Might 14th and Sunday, Might fifteenth, SparkToro’s Casey Henry spun up this complete evaluation for Mr. Musk’s account, to supply essentially the most exact quantity doable.

The breakdown of some elements utilized in our spam evaluation system is above, and in complete, 70.23% of @ElonMusk followers are unlikely to be genuine, lively customers who see his tweets. That is nicely above the median for pretend followers, however is unsurprising (to us, not less than) for a number of causes:
- Very giant accounts are inclined to have extra pretend/spam followers than others
- Accounts that obtain nice offers of press protection and public curiosity (like ex-President Trump and Mr. Musk) have a tendency to draw extra pretend/spam followers than others
- Accounts that Twitter recommends to new customers (which frequently contains @ElonMusk) are inclined to get extra pretend/spam followers
When in comparison with the distributions of different Twitter accounts, @ElonMusk’s pretend/spam follower depend could appear out of the abnormal, however we don’t imagine or counsel that Mr. Musk is immediately chargeable for buying these suspicious followers. The more than likely rationalization is a mix of the elements above, exacerbated by Mr. Musk’s lively use of Twitter, the media protection of his tweets, and Twitter’s personal advice programs.
We additionally performed an evaluation of solely these 26.8M @ElonMusk followers who’ve tweeted within the final 90 days. This filter matches the one we utilized to the Followerwonk dataset and the random followers of @Twitter.

This extra selective evaluation discovered 23.42% to be seemingly pretend or spam, a quantity not far off the estimated, world common.
Why Ought to SparkToro & Followerwonk’s Methodology Be Trusted?
The datasets analyzed above (save for the random 100 followers of @Twitter, a technique we don’t endorse) are giant sufficient in scope and rigorous sufficient in course of that their outcomes are reproduceable by any Twitter researcher with related public entry. We invite anybody to copy the method we’ve used right here (and describe in additional element under) on their very own datasets. Twitter offers data on their API choices right here.
Followerwonk chosen a random pattern from solely these accounts that had public tweets printed to their profile within the final 90 days, a transparent indication of “exercise.” Additional, Followerwonk usually updates its profile database (each 30 days) to take away any protected or deleted accounts. We imagine this pattern is each giant sufficient in dimension to be statistically important, and curated to most intently resemble what Twitter may take into account a monetizable Each day Energetic Person (mDAU).
SparkToro’s Faux Followers evaluation take into account an account pretend if it triggers quite a few alerts SparkToro exhibits in our Faux Followers software:

Our mannequin for figuring out pretend accounts comes from a machine studying course of run over many tens of hundreds of identified spam (and actual) Twitter accounts. Right here’s how we constructed that mannequin:
In July of 2018, we purchased 35,000 pretend Twitter followers from 3 totally different distributors of spam and bot accounts. Our distributors had these accounts observe an empty Twitter account, created in 2016, that had 0 followers in July 2018. It took ~3 weeks to ship the 35,000 followers. Each day for the following 3 weeks, we collected information on these pretend/spam accounts.
Along with these 35,000 identified spam accounts, we took one other random pattern of fifty,000 non-spam accounts from a SparkToro’s giant index of profiles. This gave us a complete of 85,000 accounts to run by way of a machine studying course of on Amazon Internet Companies.
These 85,000 accounts had been break up into two teams with a mixture of SPAM and non-SPAM accounts. Group A because the coaching set, and Group B because the testing set to research efficiency of the fashions.
The next information was used for the preliminary mannequin era:
- Profile picture
- Profile URL
- Verified account standing
- Language
- Tweet language
- Account age in days
- Size of bio
- Variety of followers
- Variety of account they observe
- Days since final tweet
- Variety of tweets
- Variety of occasions the account seems on lists
- Location
- Show title
After a mannequin was discovered to suit the info, we analyzed the outcomes to find out options that intently correlate to spam. Unsurprisingly, no single function was 1:1 correlated with spam. However, variety of options confirmed promise when utilized in mixture. The next are examples of options that correlate to spam accounts:
- Profile picture – accounts missing these are sometimes spam
- Account age in days – sure patterns are clearly spam-correlated (e.g. when a lot of accounts created on a single day observe specific accounts or ship practically similar tweets)
- Variety of followers – spam accounts are inclined to have only a few followers
- Days since final tweet – many spam accounts hardly ever ship tweets and accomplish that in coordinated fashions
- Variety of occasions the account seems on lists – spam accounts are nearly by no means on lists
- Show title – sure key phrases and patterns correlate strongly with spam
These, nevertheless, usually are not alone, and different alerts which have first rate correlation with spam (particularly when a number of alerts apply to a single account) had been additionally helpful to construct a functioning mannequin. By way of trial and error (and, in fact, pattern-fitting) we crafted a scoring system that might accurately determine over 65% of the spam accounts. We deliberately biased to lacking some pretend/spam accounts slightly than by accident marking any actual accounts incorrectly.
It’s essential to take into account that nobody issue tells us that an account is spam! The extra spam alerts triggered, the extra seemingly an account is to be spam. Our Faux Followers system requires that not less than a handful and typically as many as 10+ of the 17 spam alerts be current (relying on which alerts, and the way predictive they’re) earlier than grading an account as “low high quality,” or pretend.
This technique seemingly undercounts spam and pretend accounts, however nearly by no means contains false positives (i.e. claiming an account is pretend when it isn’t).
Making use of this mannequin to the ~44K random, recently-active accounts supplied Followerwonk produces a top quality rating for every account, visualized under:

The extra spam-correlated flags an account triggers, the decrease its High quality Rating on this system shall be. Our conservative method signifies that we solely deal with scores of three, 2, and 1 as pretend/spam accounts, and it’s the mixture of those three buckets that produces our closing estimate, best-stated as: 19.42% of lately lively, public Twitter profiles are extraordinarily more likely to be pretend or spam.
Earlier than concluding this submit, I’ll pre-emptively deal with some potential questions:
- Are you difficult Twitter’s earnings report, saying that <5% of mDAUs are pretend/spam?
- We’re not disputing Twitter’s declare. There’s no technique to know what standards Twitter makes use of to determine a “monetizable day by day lively consumer” (mDAU) nor how they classify “pretend/spam” accounts. We imagine our methodology (detailed above) to be one of the best system obtainable to public researchers. However, internally, Twitter seemingly has unknowable processes that we can’t replicate with solely their public information.
- Does this information present Mr. Musk with motive to interrupt his acquisition settlement with Twitter?
- The 4 of us who labored on this analysis usually are not attorneys, nor are we aware of the specifics of the discussions between Twitter and Mr. Musk. We gained’t attempt to speculate on whether or not this information can have any impression past satisfying collective curiosities.
- What are essentially the most important flaws, holes, or critiques of the methodology used on this report that might make it inaccurate?
- Essentially the most salient critique is that our methodology to calculate an lively Twitter consumer is much less correct than Twitter’s personal system. We have no idea if an account logged in to view their timeline, or visited Twitter’s web site, provided that that account despatched a public tweet. We undercount lively customers whose accounts are protected, accounts that view tweets however don’t ship any, and accounts that log in and have interaction in different methods past tweeting (like favoriting or including profiles to lists).
- The opposite potential critique is our spam/pretend follower calculation methodology. As a result of we crafted it in 2018, primarily based off pattern units of bought spam accounts, it’s seemingly that extra subtle spammers and pretend accounts go unidentified by our system. We additionally bias to a really conservative measure of spam, deliberately lacking many seemingly spam/pretend accounts so as to not by accident mark actual accounts as pretend. It’s possible that our numbers are decrease than extra subtle, extra lately constructed spam evaluation fashions would present.
- Can SparkToro or Followerwonk run customized analyses of particular Twitter information or accounts?
- SparkToro doesn’t supply companies like this past the free Faux Followers software (and, after a busy few days on this challenge, our crew must deal with our core enterprise 😉).
- Followerwonk, nevertheless, presents a strong set of Twitter evaluation information in its public software, and might be able to full particular requests as long as they’re in accordance with Twitter’s phrases of use. Drop a line to [email protected] and he might be able to help.
- How ought to media or different events get in contact?
- If you happen to’re searching for a quote or produce other questions for the authors of this analysis (i.e. Casey, Amanda, Rand, & Marc), drop a line to [email protected]
Due to everybody who’s helped to spur and assist this analysis, and particularly to Casey Henry and Marc Mims, whose fast and tireless weekend work made this report doable. As large followers of Twitter’s platform, and the kindness proven by so many of us there, we’re honored to (hopefully) contribute to its persevering with enhancements.
