My ServerFault reputation suddently went down from 501 to 423. 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?
