Updated: Does this Twitter bug force anyone to follow you?
by Mike Butcher
on May 10, 2010

We’ve been tracking down some of Facebook’s little quirks and flaws lately. But let’s get back to an old favorite. Twitter, which appears to have sprung a leak as well.

Is there a bug in Twitter which literally forces any account to follow you?

The flaw appears when a user tweets this format: “accept [Twitter Username]”. So, for example “accept TechCrunch”. Magically that user appears as one of your followers. [Update: We've just been alerted that Twitter's attempts to squash this exploit is reseting the accounts of anyone who tries this exploit to a follower count of zero. Hopefully they will sort it out soon].

This of course could be quite handy. Suddenly you could boast that some of the world’s most influential followers like Robert Scoble or Barack Obama was following you.

However, there may be a flaw in the flaw, as it were.

Web 2.0 blog Webrazzi has been testing the flaw. They started getting twitter to make inlfuentials follow a fake account, @bugrazzi.

However, when I tried seeing if I was literally following bugrazzi, the bugrazzi twitter profile itself still didn’t register that I was following it, even though I could see it was in my list of followers.

You try the hack and see if you can get it to work. Let us know what happened in the comments.

Update: Twitter has got back to us, saying “we’re on it”. Gizmodo says that this only worked in Twitter’s Web interface, not on third-party apps.

    We have tried this hack, and the specified user is not following you, but your last tweet is tweeted again. :)

  • Phil

    It will be pretty amusing if there’s a way to launch a SQL Injection attack into their servers with a specifically formatted string.

  • http://twitter.com/chadsmith Chad Smith

    Either TechCrunch is now following me or it works.

  • inci sikkerr

    this bug was discovered by @borakrc and made public..so no credits to the guy and it is techcrunch who discovered that?
    check this

  • http://www.larovo.com Ulrich

    works for me :)

  • joe

    The whitehouse twitter account is following strange accounts now.

  • inci sikkerr

    the mentioned guy (@borakrc) who found this bug has followers including @tomhanks, @BarackObama , @billgates, @ladygaga, @mythbusters etc. so credits to him!!

  • http://twitter.com/dirkahlers dirk

    still works

  • http://twitter.com/ediciuz Ediciuz

    This is great (well, not really, but I’m sure you know what i mean). If only there was a way to do the opposite

  • cpnieuws

    This actually works! Why would Twitter put something like this in their code?

  • joe

    Its called Blocking ;d

  • Joanne

    Oprah Winfrey is now following me. It works.

  • Stepshep

    Well, now @ConanOBrien is following almost 70 people so I’d say it works. Wonder how long until twitter disables it…hope they have a way to revert these changes.

  • http://twitter.com/ediciuz Ediciuz

    I meant automatically follow someone else (who’s protected)

  • SellWeek

    Yep, made Mashable follow me

  • http://twitter.com/ediciuz Ediciuz

    Twitters down now that everyone is doing it…

  • http://indiepoint.net Jesse Dorsey

    I wonder what twitter is going to do to accounts that take advantage of it in retaliation.

  • Kloc

    Well I’m loading myself up with celebs as we speak just to be funny if they delete my account oh well.

  • http://dipak.org.in/ Dipak Mishra

    It worked for me. I tested it twice and I could see myself in those two people’s follow list.

  • Noah

    It definitely works, and your tweets absolutely show up on their timeline. Just tested it out with two of my accounts!!

  • lp

    Too bad they don’t use SQL anymore.

  • http://blog.gadodia.net Vaibhav

    I got @TechCrunch to follow me, and it even allowed me to send a DM to @TechCrunch – not sure if the DM was delivered though…

  • Kloc

    Lol in the case I just tweeted to a friend to look at my followers and all the people that shouldn’t be following me can now see that.

  • josh

    Works for me.

  • http://www.CrossLoop.com/WDMARKPC WDMARKPC

    TechCrunch now following me. Can you test “Unfollow” rather than Block please.

  • Zac Bowling

    They still use SQL. Twitter is still primarily SQL actually. All tweets are stored in both the old Mysql storage and the new Cassandra data store at the same time. They are ramping on who reads from Cassandra and who reads from MySQL/Memcache while they stress test Cassandra.

  • http://beaugil.es Beau Giles

    Working here – thanks for following @BeauGiles @Techcrunch. ;-)

  • sr

    built a bot, cycled through top 1,000 users. I am now being followed by oprah, techcrunch etc.

    The person who found this should have kept quite and done this themselves.

  • http://www.twitter.com/nknauth Neil Knauth

    Wil Wheaton is now following me.

    There’s one celebrity who I want to follow me, but… I’d feel guilty, y’know?

  • http://www.rukshan7.blogspot.com Rukshan7

    it really works, Bill gates and the NASA is following me now

    Any one who had this done to them, are you receiving updates or seeing them in your list?

  • http://2009Taxes.org Steve @ 2009 Taxes

    Next time just email a couple people with this kind of useful information.

  • http://www.twitter.com/MacSmiley MacSmiley

    This bug allows you to “accept” someone who’s blocking you, thereby removing the block.

    I doubt it unlocks anyone’s protected tweets, though. Or does it?

  • flip

    Actually this bug could be converted into a hack. I mean, BH will go crazy over this exploit. Hopefully twitter will put a patch on these bruises.

  • http://beaugil.es Beau Giles

    Touché

  • http://indiepoint.net Jesse Dorsey

    Did anyone elses followers / following numbers turn to 0?

  • sr

    It looks like they fixed it; lost all my newly found celebrity followers :-(

  • mike

    everyone just turned to zero. we killed twitter

  • Stepshep

    Twitter retaliates by dropkicking your followers and followees to zilch!

  • http://sluuggo.com Sluuggo

    Nice, went from 13000 to 0.

  • http://www.kellykarnetsky.com kels

    I just did this to TechCrunch, it worked, but now it says I’m not following anyone and no one is following me.

  • http://blog.gadodia.net Vaibhav

    WTF? Twitter just reset my followers and following to ZERO

  • http://methodicjon.com MethodicJon

    Seems twitter has blocked this, and un-did follows.

  • http://www.terracecrawford.com Terrace Crawford

    Oh crap! Does it break your twitter? I just tweeted “accept conanobrien” and now the # of my followers and those i’m following display ZERO!

    I hope this hasn’t screwed up my twitter account.
    Anyone else experience this???

  • http://www.1blogger1.com Mark

    I wish I never stumbled across this now. They just deleted all my followers and the people I was following.

  • Scott

    @Terrace Crawford

  • Fernando

  • http://twitter.com/ediciuz Ediciuz

    Every single person is at zero (but the tweets still show up from ppl you follow) so I assume it’s only temporary

  • http://www.CrossLoop.com/WDMARKPC WDMARKPC

    Yup, I’ve lost all my followers…Ouch for this Beta Test.

  • http://phenomate.com alex

    My followers/following counts are zero as well and I did NOT tinker around with the hack at all. But still getting tweets from people I’m following.

  • http://orchid1software.com orchid1

    yup it show up that no one is following me as well and I am following no one
    oops! Haha

  • http://zerocostoffers.com freebie offers

    glad I didn’t do this………………..

  • Roy

    The entire twittersphere went down to 0 followers, following 0. Timeline still intact. @twitter just tweeted: “Follow count display is set to 0 and follow/unfollow is temporarily offline while we fix a bug.”

  • http://www.gbnet.net Steve Kennedy

    It seems while fixing it there was an “internal server error” which also leads to your follower count and following counts to be reset to zero (and no followers or following people are visible), however you still get tweets.

    Well, they reset me and I didn’t even know about the bug until 5 minutes ago. So, they aren’t just doing it to people who try it out.

  • I Just Lost My Followers Too

    I just lost all of my followers as well as the people I was following by testing this bug.

    I hope twitter will restore those, otherwise what a terrible accident!

  • Gentry

    Gizmodo says that this only worked in Twitter’s Web interface, not on third-party apps.

    Gizmodo is incorrect. I got it to work using Tweetie 2.

  • josh

    Gizmodo was wrong. I added about 6 people from Tweetie. Maybe I’ll sell them my iPhone…

    “Gizmodo says that this only worked in Twitter’s Web interface, not on third-party apps.”
