This question already has an answer here:

Could someone take a look at my (main user) profile and shed some light on the 70 reputation that went missing today? It simply states "user was removed". Thank you!

    $\begingroup$ This MSE thread may provide some more up-to-date information than the linked meta.math.SE thread, but the basic idea is the same. An account was deleted (without too many votes), and the total amount of reputation that user had given you was 70. $\endgroup$ – user642796 May 30 '14 at 19:33

    $\begingroup$ If it makes you feel better I lost 200. Sad, but such things happen. $\endgroup$ – Jyrki Lahtonen May 30 '14 at 19:41

    $\begingroup$ I was a bit curious so I did a bit of digging. Most people at the top lost quite a bit except Amy, Lab and Ron. Matt E and Mariano lost over 300 and Georges lost over 1000 points. Looks like whoever was removed was heavily into algebra/algebraic geometry. $\endgroup$ – Jyrki Lahtonen May 30 '14 at 22:20

    $\begingroup$ [Looks like whoever was removed was heavily into algebra/algebraic geometry.] Agreed. I lost 506. $\endgroup$ – Makoto Kato May 30 '14 at 22:32

    $\begingroup$ @JyrkiLahtonen removed user... I am surprised that the SE team did not keep the user's votes: 4003 up and 1659 down. $\endgroup$ – user147263 May 31 '14 at 2:10

    $\begingroup$ @ArthurFischer: The data above means that the deleted user had given enough votes to make it to the first page of all time voters. Looks like the bar for not removing the votes is quite high!? $\endgroup$ – Jyrki Lahtonen May 31 '14 at 10:17
  • $\begingroup$ @JyrkiLahtonen The process for determining that the special deletion procedure is used seems to be rather improvised. It has happened before that the SE employee deleting the user missed that the user had a large amount of votes. $\endgroup$ – Mad Scientist May 31 '14 at 17:27

    $\begingroup$ @MadScientist Did they ever un-delete the votes after recognizing the mistake? $\endgroup$ – user147263 May 31 '14 at 17:32
  • $\begingroup$ It seems to me that when a user is deleted, her upvotes should not be necessarily be deleted, unless her upvotes are the reason for deletion. Perhaps too complicated for a program! $\endgroup$ – André Nicolas Jun 1 '14 at 1:43

    $\begingroup$ @AndréNicolas Most deletions are at user's own request (I guess this one was too), and they are handled manually by the SE team. So it's more of a policy issue than a programming issue. The most upvoted feature request in the history of SE is Don't throw away all votes when a user is deleted, and it's neither declined nor implemented fully. $\endgroup$ – user147263 Jun 1 '14 at 2:03
  • $\begingroup$ @wordsthatendinGRY yes, they have done that at least once. It was a more drastic example though because it was on a beta site where the average rep is lower, and the impact of deleting many votes higher. $\endgroup$ – Mad Scientist Jun 1 '14 at 7:27
  • $\begingroup$ @MadScientist Thanks; here is another example of reversal, on SO. I dropped a note to the SE team asking for the votes to be undeleted, based on the stats. He was in the top 0.03% of voters... $\endgroup$ – user147263 Jun 2 '14 at 0:42
  • $\begingroup$ Was this just overturned? I received an unexplained 200 rep out of thin air, and this was the first thing that occured to me as a possible explanation. $\endgroup$ – Jyrki Lahtonen Jun 9 '14 at 19:56

    $\begingroup$ @JyrkiLahtonen Yes. About an hour ago SE replied to my request with "These will be restored." The delayed response was probably due to their data center relocation. Interesting that your and others' timelines still show reputation drop on May 30. This may be recalculated later. Or not. $\endgroup$ – user147263 Jun 9 '14 at 20:24
  • $\begingroup$ @JyrkiLahtonen It did get recalculated: the drop on May 30 is gone from the reputation timeline of the affected users. $\endgroup$ – user147263 Jun 10 '14 at 6:31
