Pvp Manipulation
Well the obvious thing to state first is this thread will be deleted soon due to name shaming. As far as adding him to the block list to avoid him, you have to wait until you see he is in a match (such as it will tell you he is in Foefire map) before you queue if you want to avoid him.
I think the name thing is a vestigial rule, people should be blacklisted and other players warned about accounts with excessive toxicity and throwing going on.
It’s special place Will be the trash since you posted their account.
