That could happen, but just because that might happen shouldn't mean you exclude it. You could also give advice to people, congratulate them on a good reset/game/match/name, and more. I think the positives could outweigh the negatives
I come from a dota/league background and this community is far less hazardous. Either way, I'm all for letting the rage commence.
Never let a few bad apples spoil it for the bunch.
