@MassimoOrtolano, or another mod. Is there some sort of methodical down voting going on in the last few hours? Is someone behaving badly? Maybe it is worth a check.
@Buffy SE's bot to catch malicious voting is really really good at it, but only runs once every 24hr (probably the specific time is posted somewhere on Meta)
meta.stackexchange.com/questions/126829/… "Please do not try to get help on this issue on meta or by flagging for a moderator. All they will do is tell you to wait for the voting fraud script to run (they can't run it for you just this once)."
@Buffy Yeah, I partly jumped in for Massimo's good, too, wasn't sure if he was familiar and hoped to save him some time (since there isn't really anything for him to do at this point).
Sometimes I write things that would be controversial, but none of the recent stuff seems to be like that. Usually I can predict my posts that will draw down votes.
