@NoomphyMop It can be frustrating, for sure, but death penalty seems too much lol, never mind banning. I suppose it could depend on situation and that in some cases it could fall under harassment and banning is justified according to ToS. That would require you being singled out as target and hunted out throughout a match, or across matches even. I dunno..
I think most do it because they feel bf they did something cool and deserves some credit.
Also I wish we could find a less obscene way of gloating. I usually jump in place a few times when I think my kill was extremely skillful (read: lucky).
