Reposting my responses from your original thread that you deleted.
People who tell others to kill themselves are definitely banned and in fact it's one of the ZTP things that can escalate straight to a 14-day ban first offense. There are countless threads in PB alone that prove as such. That said I personally have never encountered people telling others to kill themselves in any of my games since I started playing in S2 (doesn't mean they aren't out there), so perhaps you're just unlucky in that regard. Also, other people behaving poorly does not give you a free pass to do the same.
First of all relying on getting that popup notice is foolish as not only is it notoriously unreliable but it also doesn't prove whether someone got punished or not.
Second of all you shouldn't go stalking the profiles of those you reported as not only is it a waste of time and petty but if the person you're stalking got a chat restriction then you stalking their profile would prove nothing anyways since CRs don't stop someone from playing the game.
Third of all, my comment related to retaliation was more of a general purpose reminder here more than anything else. Apologies if I didn't make that clear before.
