First of all, i want to report Heap_OverFloww who is violating a rule that says you can't have a misleading handle. This user is impersonating Heap_OverFlow and trying to frame him.

My question is, how do i report situations like this and to who? I tried searching for it, but failed to find anything. I don't think making a blog for each particular case is a great idea. Would like to hear your opinions on it and maybe get official answer!

UPD: AkiLotus shared information reporting system. Here is an official blog. The reporting is available only for Div 1.
