There's one angry user who leaves comments with obscene language on my questions http://stackoverflow.com/users/207177?tab=activity#tab-top (actually, he also downvotes me and some other users as 'for the great justice').
I don't care about downvotes but I don't want to see those comments on my questions especially because it's a public resource which were outstanding among other with its civilized educated community.

UPD: he's amnestied today. And coincidentally I've got 5 downvotes on 5 of my questions without any reasining. Questions are listed below (I've already flagged them):
