Is there any way for me to see who is upvoting or downvoting me? Apart from looking at the data dump, of course.

No, I will not go after those who downvoted me, but it's interesting to know, anyway.

  • Lately I've often been thinking that it would be nice if I could see that I was downvoted in the first place. – innaM Oct 28 '09 at 9:47

    @Manni - This is shown as part of you voting data in the envelope view. It will show all up and down votes. Unless your looking for something else? – BinaryMisfit Oct 28 '09 at 10:02

    I feel bad enough downvoting as it is, and while I always try to leave a comment, sometimes I just can't bring myself to do it :( – Phoshi Oct 28 '09 at 11:28

    Explaining a downvote is not without risk. Sometimes you get a string of downvotes on old answers in return. – Andomar Oct 28 '09 at 12:40
  • @Diago: I am talking about the envelope-thingy, yes. But I have my doubts about its correctness. I'll keep an eye on that thing an report a bug when my suspicions are confirmed. – innaM Oct 28 '09 at 12:41

    @Andomar: That is true, unfortunately. But it shouldn't keep you from explaining your downvotes. I suggest to report revenge downvotes immediately. – innaM Oct 28 '09 at 12:43

    What?! -2 points? Now I have another reason to know who downovoted me, and why :) – Graviton Oct 29 '09 at 4:01

    +1 I wouldn't mind my own downvotes being visible. If I don't leave a comment its because I'm lazy, not because I'm afraid of revenge voting. – Perpetual Motion Goat Feb 5 '10 at 8:22

    +1, there really should be a rule about leaving a comment when you down vote. i just had a down vote and run for one of my questions and it is completely non-constructive. i don't particularly care who did it but what is the point of a down vote if there is no explanation as to why i got it? i can't change whatever the person had a problem with without an explanation so to me that is just someone being a d*#@ for no reason. – Ozgur Susoy Apr 26 '14 at 14:17
  • I actually don't care who voted down, but why. So it would be nice if a down vote would only be possible after leaving a comment. SO asks to add a comment, but it does not require it. That's bad. – qwerty_so Jan 28 '15 at 20:40
  • I'm working on a Java application that tracks this. I will release the source on GitHub shortly. There are too many comment-less / serial downvotes for this to be a good system otherwise. It's simple to track by measuring the -1 cost of a downvote and the timing of the downvote. – Hack-R Sep 6 '16 at 0:55
  • @Hack-R, how can you do that when the data that you can access is already anonymous? – Graviton Sep 6 '16 at 2:27
  • @Andomar Never fear, the StackExchange serial downvoting system is here! They'll take care of your serial downvotes, so no worries! – Unitato says Reinstate Monica May 27 '17 at 17:09

No

Voting is anonymous and not even the moderators have access to this information. The only people I suspect that can see is the Stack Exchange development team.

From the comments: Voting data is made anonymous before the data dump is done so this information is not available in the data dump.

Clarification

There are scripts that run that check for voting anomalies that will indicate when a user has a high rate of up-votes or down-votes from a particular user, however these instances are rare and handled by the team.

    I don't think this information is available in the data dump, as this would defeat the anonymity. – fretje Oct 28 '09 at 8:50

    correct - voting data is anonymized pre-dump – warren Oct 28 '09 at 9:46

    what exactly does high rate mean? and how often does this script check run? – Aditya P Mar 14 '11 at 4:57

    @AdityaGameProgrammer: The details of the anti-serial-voting script are not really publicized (lest people try and game the algorithm), but e.g. two accounts upvoting each other all day long will be probably caught by this. – Piskvor Apr 8 '11 at 18:02
  • @Piskvor fair enough.But if a person really wanted to game it observation and analysis would be enough to figure it out for most part. – Aditya P Apr 8 '11 at 18:08
  • However, not forcing someone to leave a comment when downvoting will not be helpful to the guy whose answer was downvoted. He will be clueless as to why a perfectly valid answer (according to him) was downvoted.. – Onkar Aug 15 '12 at 14:17

Confirmed that the Upvoter / Downvoter UserId's are zapped from the Votes table, e.g. by running this data.stackexchange query. Note however that 'favourited' and bounty Userid's seem to be retained :) (Thanks, mom!)

SELECT v.UserId, vt.Name, COUNT(*)
   FROM 
     Posts p
       INNER JOIN Votes v
         ON v.PostId = p.Id
       INNER JOIN VoteTypes vt
         ON v.VoteTypeId = vt.Id
  WHERE
     p.OwnerUserId = ##UserId##
  GROUP BY 
    vt.Name, v.UserId
  ORDER BY 1,3

    If someone has the balls to downvote against someone who made the effort, they deserve to get a reason or condition to improve. Often the critic is ill informed or ill-willed if silent – Tony Stewart Sunnyskyguy EE75 Dec 30 '16 at 8:08

    All self-styled Einstiens have this problem of downvoting questions and answers in a rush, to prove their superioty and that too without an explanation. Recently I have been a victim of the same. I do not know WHY downvoted. – Mopparthy Ravindranath Mar 29 '17 at 5:51

    Having around 13 upvotes on an answer, I am still thinking what went terribly wrong for that person who downvoted without even having the courtesy to explain. – Pranav Karnik Oct 12 '18 at 12:06

    SO should develop this functionality, those who are downvoting, before that they should post a reason to downvote. – Rahul May 8 at 13:02
