This question already has an answer here:

For people who are trying to close this: Its Serial negative group voting..
I am aware of automatic detection script but looks like it fails in such scenarios.


Many times I was a victim of serial downvoting. But SO is pretty awesome to detect and revert it

enter image description here

But looks like now a days downvoter have become more awesome,I am facing short number of sudden negative votes. And looks like same person with multiple profiles is doing this
enter image description here

I am not saying I am too genius to receive downvotes but
1. The questions are almost 2 year old and never received any downvote before.
2. All of a sudden in 3 mins how can 3 or more random people downvoted on my old questions? (Looks a very low probability case)

I am not afraid of downvotes but just hate when someone gives it without any reason.
Do SO take any action against such things?


Looks like even the downvoter is reading this post. Few more rewards after taking this up

Year old questions and all of a sudden downvotes.

Looks like three different users have downvoted your answers in from the same computer. ( resource : voting pattern ) –  Raynold Mar 12 '13 at 11:21
    
@Raynold: Ya minimum 3 or maximum 6 different accounts.But I guess only one evil mind behind it. –  Karna Mar 12 '13 at 11:24
    
No, it cant be 6 different account. The voting time says that part. –  Raynold Mar 12 '13 at 11:25

"Many times I was a victim of serial nonvoting." Huh? How does SO revert that - by giving you votes? –  slugster Mar 12 '13 at 11:25

@slugster: By reverting I mean undoing negative votes. Check first image in my post. –  Karna Mar 12 '13 at 11:26
    
@Karna, dowvoter is only downvoting your questions, not your answer –  Raynold Mar 12 '13 at 11:30
    
@Raynold: Still it hurts a lot.. –  Karna Mar 12 '13 at 11:37

@Karna, i know, what i am saying is, if anyone downvotes your answer then he/she looses -1 from their reputation, that's why these users are downvoting your question only. I assume these users have very less reputations like > 125 and < 200. ( its only my assumption ). –  Raynold Mar 12 '13 at 11:39
    
@Karna: I thing slugster was referring to the term 'nonvoting'. :-) I know you ment down votes, really. A 'nonvote' is the absence of a vote, reverting the absence of a vote suggests you were given a vote. :-P –  Martijn Pieters Mar 12 '13 at 11:44
    
@MartijnPieters: Oops my bad. it was a tyop :) Updated my post. –  Karna Mar 12 '13 at 11:45
    
@Raynold: Ya smart old fashioned villain.. –  Karna Mar 12 '13 at 11:47

Sounds somebody is not happy with you... I flagged one of the questions with a link to this discussion. Hopefully it will be solved soon. –  Toon Krijthe Mar 12 '13 at 11:50
    
@ToonKrijthe: Thanks for flagging. Hope I will get my hard way earned reputation back. –  Karna Mar 12 '13 at 13:57
    
I think I am experiencing something similar, but a little too early to tell. Had a few of my questions suddenly down-voted in a short space of time, included a lot of old questions that haven't had any attention in some time. –  Rudi Kershaw Jan 6 at 9:32

up vote 20 down vote accepted

That does indeed look very suspicious and may evade the serial-voting script.

If, after 24 hours, the downvotes have not been reverted, flag one of the posts for moderator attention.

Use the "other" option and explain, and a moderator will investigate. If there are sockpuppet accounts involved they have the tools to detect these and clean up.

Its already been more than 24 hours. Will try flagging..I think others must be suffering from such lame attacks so don't we have anything to detect and prevent it? –  Karna Mar 12 '13 at 11:17

There are automatic scripts that aim to reverse such cases. They sometimes slip under the radar. In that case, call a human exception handler (a moderator). –  Second Rikudo Mar 12 '13 at 11:35

@Karna: We already detect serial downvoting, but automated detection can only go so far. In the (rare) cases where it fail to detect a specific anomalous pattern, the moderators can step in. –  Martijn Pieters Mar 12 '13 at 11:37

@Karna if you flag, consider also referring to this meta question in your flag message; that way it would be easier to moderators to get the background and discuss details of the issue –  gnat Mar 12 '13 at 12:00
    
@gnat: Yes already flagged and added link to this post. –  Karna Mar 12 '13 at 12:01

I saw a flag someone had raised on this, and tracked the source. You were indeed being targeted by a user and his two sock puppet accounts. I destroyed these sock puppets, which looks to have eliminated all of the targeted downvotes here.

Given that these sock puppets were being used to vote for their own posts, and this is not the first time they've done this, I gave them a lengthy vacation from the site.

If you see suspicious behavior like this in the future, please flag us about it and we'll take a look into it.
