I got permabanned for responding to trolls. Riot's response is disgusting.

I was lagging and some trolls decided to start trash talking me for playing bad so I responded. Then a few days after my permaban, I said on the forums that if I don't respond to the trolls I will have pent up anger and cut myself. Riot's response to this was to delete that comment and ban my account from the forums for 7 days. And said the reason for that was because the comment was racist and homophobic. This is how they deal with people on their game making other people want to commit suicide. They just sweep it under the rug so nobody finds out. Mods are you retarded? What if I was still upset from having my account that I've worked hard on for 4 years becoming permanently banned? I might have killed myself if I was still upset. But I'm actually glad that my account got banned because this game is horrible. It's full of trolls and I lag on it because Riot are cheap with their servers. I don't lag on any other game so I know it's not me. Riot doesn't care if their game and the people that play on it make me want to kill myself. They will probably just delete this thread too and pretend I don't even exist.
