Over on scifi.meta.SE, there is a question with lots of answers by the same person which are options for users to vote on.
General note to voters here: since this thread contains many answers by the same person, if you vote on all of them too quickly, your votes may be invalidated by the system (thinking it's "serial voting").
However, since community wikis don't earn the user any rep, would multiple quick votes on community wiki answers count as serial upvoting?
From the wiki page on serial voting, the mechanics are secret - is it possible to get any details on this?
Every night around 03:00 UTC, a voting fraud detection script is run that looks for patterns such as these. It basically looks for users who have voted on another user's posts many times. The threshold number is fairly low within a given amount of time (the exact mechanics are kept secret). When the system detects this pattern, all of the votes cast from that user to the user affected are reversed, and a "voting corrected" event is added to the affected user's reputation history to indicate what has occurred.
