It does not seem to be the result of many downvotes (or they are well hidden). In the past, I remember that big cleanings of reputations took place in StackOverflow, after massive cheating was detected. But I find no such announce for ServerFault and, anyway, I do not cheat :-) Any idea of what is going on?
