Nobody bothered to answer my edited question yesterday. So I'll write a new question but ask about the same things.
In less than a month I have had rep points reversed three times. I'd like to know what is StackExchange's policy concerning serial upvoters. Presumably the mods know who this or these persons are. Does the person who upvoted thirty questions in under five minutes yesterday know that his/her votes have been reversed? Are they penalized in any way?
Presumably, the happy serial upvoter is someone who has earned at least 15 rep points, the minimum number of points necessary in order to gain the privilege of upvoting answers, so it can't be a complete outsider. I can't believe it is a veteran user but anything is possible with sockpuppets. My instincts are telling me that the behaviour is ironically, malicious, and I'm guessing it's the same offender. Am I right?
