I used to have 291 reputation on StackOverflow, now I have 467. It seems like somebody upvoted many of my answers in one day...
I don't want people to get suspicious on me, what can I do?
Can I find out who did the upvotes?
This is all handled automatically; you don't have to do anything.
If voting anomalies persist for more than 24-36 hours email us at the address provided at the bottom of every web page, with as many details as you have.
I'm the responsible of that BlaXpirit, I can remove my up votes if you prefer. I think we should not be able to upvote the same people too many times.
