I recently came across a question and I saw the vote counter was updating as usual when people up-vote it.
But then I saw it was really another user upvoting, downvoting, upvoting, etc.
I joined in and had a blast. The other person would wait till I upvoted, then they would do do something to the vote count count, then I'd undo my upvote, and so on until they abandoned me :(
It was probably the most fun I've had at my job in awhile.
Shouldn't there be some form of rate limiting for this?
