About 10 minutes into the "day", I started receiving a long sequence of single votes on questions There are 28 upvotes over a period of 2-3 minutes. Moreover, they occurred on my answers in almost precisely the inverse order in which they appear in my profile when listed by number of votes (a few answers seem to have been skipped). Then they stopped shortly after they hit my reputation cap.
Not that I mind getting votes, but this seems almost like "spam upvoting", someone who decided they wanted to 'reward me' by upvoting my answers, regardless of what those answers say. If it was indeed one person, there is simply no way that those votes can reflect an appreciation of the answers themselves, because there is no way the answers were read in those two minutes.
I'm not really sure what I'm trying to say; except that it all makes me feel rather uneasy. If the moderators could check if it was indeed a single person just "serial-voting", then perhaps that person could be contacted. I don't think serial up-voting is any better than serial down-voting.
Or maybe I'm being overly sensitive; it just seems like I didn't really "earn" those votes.
Update. The votes (and rep) seem to have now "gone away."
