Instead of putting in ignorant and annoying pop-ups when some trolls spam reports on someone they've pissed off, you should work on your matching system that puts these feed-N-leave/trash talker style trolls on people's teams ten times in a row until we're obviously not going to want to pamper their feelings with nice comments. League of Legends did this dumb shit in 2015 and surprise surprise, lost millions of their supporters.

So work on your matching system, let those hypocrite trolls use the ignore button if they don't like the truth, and while you're at it, you could quit rewarding the useless assassin players that do nothing but wait til the rest of the team does all the work and then do some tiny amount of damage to end with more gold than someone who dealt four times their damage and died 1/10 as much.
