According to the help page, e.g. on Stack Oveflow (emphasis is mine):

All the reputation changes from a single user's deletion are rolled into a single event in the reputation page labelled "User was removed".

But I see multiple events in my profile on Stack Overflow in Russian:


One message (20:41) says "User was removed", and the rest (all 20:40) say "unupvote". For most posts unupvoting is not possible due to lack of post edits, i.e. vote should be locked on them. Hence I think it's a bug.

  • Try waiting for some time, see if it gets folded in. It could otherwise be voting fraud being reversed. Either way, we need an SE employee to investigate. – Sonic the Anonymous Hedgehog Jan 19 '18 at 15:47

It looks as if voting fraud was reversed here. The user may have serially upvoted you, and that was undone - either by the script or manually by a Community Team member.

When the serial voting detection script reverts votes, it is usually rolled into a single event, as Sonic points out in their comment. When a CT member needs to get involved, they may have to investigate the suspicious votes separately, hence this resulting in separate unupvotes/undownvotes.

It is very well possible that the serial voter is the same user that got deleted, but it doesn't have to be.

    If it was serial voting, it would show a single statement "voting corrected", not a bunch of different "unupvote" statements. – Sonic the Anonymous Hedgehog Jan 19 '18 at 15:48
  • @SonictheAnonymousHedgehog On one occassion, some serial voting on my own profile on SO was not undone by the script. I flagged for moderator attention, and a few days later the serially voted posts got un{up|down}voted. – S.L. Barth - Reinstate Monica Jan 19 '18 at 15:49
  • It likely only applies if it's automatically undone by the script, then. – Sonic the Anonymous Hedgehog Jan 19 '18 at 15:51

    It was probably undone by a moderator because as far as I know, the script only runs at 3.00 UTC, and here the voting was reversed at 20.40 UTC. – Donald Duck Jan 19 '18 at 17:27
