I read one answer that stated not to ask about this on the meta site, within 48 hours. But I don't know how else to contact a moderator. And also I think it might be a bug.
I lost 35 reputation points last week, without a known reason, just with the message "Serial voting was reversed". I read something about voting fraud, which I'm not aware off. I did got -35 points at a moment where I asked several questions in quite a short timespan.
Is it possible that the amount of "up votes by the same user" are not relative to the amount of recent questions but a static "low" threshold that could cause the anti-voting fraud script to reverse the votes because it flags it as "one user upvoting another user too much in a short time?".
As far as I know, I don't know anybody on this site personally and won't see a reason why anybody would upvote my questions or answers suddenly a lot.
Also, the lack of information is a bit annoying. I don't know what user did so, I also don't know on which of my questions or answers this is flagged.
Can someone look into it please?
