Checking my recent activity, I noticed that [nearly] all of my posts were downvoted within a short span of a few minutes. It seems as though I've been the victim of a systematic downvoting spree.

What can I do if I suspect that someone has downvoted all my posts in retaliation or revenge? Is there something in place that will stop this kind of voting abuse? Do I have any possible avenues of recourse?

    Doesn't look random to me--they look systematic! – Stu Thompson Sep 13 '09 at 9:50

    Well yes, of course. They're systematic because they appear to come from one single user, but they're random because the questions and answers that were downvoted seemed picked at random (except of course they were all mine). – Philippe Leybaert Sep 13 '09 at 9:52

    @random Answers man. Those were answers. – random Sep 13 '09 at 10:31

    The good news is... I have tracked what I believe to be the culprit. I will discuss it with the team... I also think (not sure) that those downvotes have been cancelled. – Marc Gravell Sep 13 '09 at 22:01
  • Thanks Marc. I suppose I'll never know who's responsible for this, will I? BTW: the downvotes are still there. I don't really mind, but I'd hate to see it happen every day though. – Philippe Leybaert Sep 14 '09 at 5:44

    Happened to me 'bout an hour ago - 4 downvotes on my highest answers, inside of a minute. Yet to see a reversal, but do the downvoters get their rep back too? – OMG Ponies Mar 3 '10 at 0:35

  • Hey, I'm also in a situation of constant downvotes for no reason at all... – user447378 Mar 10 '19 at 9:27

It just looks like you have gotten on the wrong side of somebody, and they have went on a downvoting rage against you.

SO runs scripts and checks for this kind of behaviour every 24 hours, so it should be fixed up soon.

    That's what I thought at first, but after checking all the downvoted answers, I couldn't find anything that could trigger this kind of behavior. The human race is a weird bunch of animals sometimes :) – Philippe Leybaert Sep 13 '09 at 9:48
  • True that. Someone, somewhere, was so unhappy with you that they said to themselves "I'll show him!" and went off on a down vote rampage. – Stu Thompson Sep 13 '09 at 9:52
  • The downvotes disappeared. Either the script has just run, or someone intervened and removed the downvotes (Or the downvoter came to his senses) – Philippe Leybaert Sep 13 '09 at 10:05

    The downvoter couldn't "come to his senses" since the vote reversal time limits were in play -- unless you'd edited every single one of those questions & answers. However, I am glad the script is working out nicely there. Revenge downvoters suck. – John Rudy Sep 13 '09 at 15:03

As already stated, there are automated processes to watch for this. Checking in a few places (your "recent" tab on SO, Jon's SO tracker, etc), it looks like this may have already been undone by the system.

If you think there is still a problem, flag for a ♦ moderator (or add a comment here), or e-mail the team (page footer). BTW; it makes it easier to investigate if you associate your SO/MSO accounts, plus you get free rep ;-p

  • It happened again half an hour ago. I took your advice and e-mailed team@stackoverflow.com. This is really sick. – Philippe Leybaert Sep 13 '09 at 20:27
  • or add a comment here? Some fellow just downvoted me a grip for downvoting one of his posts after commenting to me on it that it's a past-time of his to downvote people who downvote him.. Think you could fix it up for me? – Jimmy Hoffa Aug 25 '10 at 19:12

    @AnoopVaidya dealt with, thanks – Marc Gravell Mar 23 '13 at 7:40
  • @MarcGravell: Thanks Mark for reversing. Seeking another help - is there any way to know, who is/are the serial downvoter(s)? – Anoop Vaidya Mar 23 '13 at 7:51
  • @AnoopVaidya by me (and ♦ mods), yes: and I've already contacted the individual(s) responsible on the matter. – Marc Gravell Mar 23 '13 at 8:08
  • @MarcGravell Someone went on a downvoting spree yesterday and I was in their crosshair. It's been over 24h since it happened so do you mind taking a look at it when you got the time? – mekwall Jul 8 '13 at 16:27

Serial-downvoting is a consequence of any anonymous community -- and there are systems in place to combat it. It is frowned upon, and I'm sure that if the user did it repeatedly they'd be asked (politely) to stop.

If you feel you've been the target of serial downvoting, flag one of your posts for moderator attention, and ask for a rep-recalc.

Also, there's an automated system that performs a vote 'undo' when a certain pattern of downvoting is seen, this could also be triggered.

    Attribution? That's George's answer, lock stock and barrel. :) – John Rudy Jan 13 '10 at 15:11
  • And, that is exactly why you should upvote it rather than disrespectfully down-voting. Do it for Georgie. – Evan Carroll Jan 21 '10 at 16:26
  • I wasn't your downvoter here. – John Rudy Jan 22 '10 at 19:25

    Why was this downvoted, its not wrong and has some useful tips/info. – mPP Dec 7 '10 at 3:43

    @EvanCarroll +1 for Georgie – Michael Oct 5 '13 at 3:42

Looks like you made enemies with some other user who is now downvoting your stuff. Contact the team (Contact us link at the bottom) so that they can reverse it any educate that user about the penalty-box.

Edit: Or not, wasn't aware of the automated checks. Leaving this here just as a sign of what not to do.

    Philippe should wait to contact them. joshhunt is correct...SO is actively looking for these behaviors and it very well may be remedied soon. – Stu Thompson Sep 13 '09 at 9:49

Just suffered a similar "storm of downvotes" myself, in the space of one-two minutes about an hour ago -- "just" nine of them, in my case, not twenty like Philippe had, but similarly "random fury" (the downvoter hit several of my questions and a random-ish sample of my answers). I will patiently wait for the cleansing script to run, and hope the script in question doesn't have a threshold of ten to identify "sabotage downvotes"!-).

    Oi, don't go throwing names around like that willy-nilly. – random Nov 8 '09 at 3:14
  • I have a sudden urge to rename myself. – mmyers Nov 8 '09 at 7:03

    ...and the script has apparently done its job now, the "sabotage downvotes" are gone. – Alex Martelli Nov 8 '09 at 16:26

Happening to me (second time) now... this time it seams like a reply to a comment I did (just pointed a little error in the answer code). First time was because of a downvote I did (60% - 80% fixed).

But who cares, I lost 10+ received 100... and someone else got his revenge for my - just wanted to help - comment.

EDIT 2010-01-01:
seams like someone really got hurt :-(
5 additional down-votes this night/yesterday...
kind of childish.

  • If it's a significant amount it'll get picked up by the automated systems and the down-votes removed and the rep restored. – ChrisF Dec 30 '09 at 20:54
  • I think there's no need, seams like the down-votes where removed (eventually 2 left). – user141148 Dec 31 '09 at 16:43
