Permanent Suspension Isn't Right
Please listen to this with an open mind. This has gotten me thinking long and hard, and there needs to be a better way.
This hasn't happened to me, but shit. It's worrying. Think about it, guys. Some people really do have problems with toxicity. You don't know if someone has Tourette Syndrome or something. You don't know if their parents divorced, or if their dog killed himself. Not everyone is just a troll; some people just can't help it.
I'm not saying to go easy on toxic people. No one would ever dare agree with such a horrid idea. I'm just saying, no one should lose their entire account because of it. People spent their money on this game; they own skins that not everyone has, because they enjoy the game that much, and it made them feel good, and special. Banning them won't keep them away. If they really do enjoy the game, they'll make a new account and come back, only without the skins they spent their money on.
What I propose is this. Don't ban them. Reset them. Bring them back to level 1, remove their champion mastery, and ranked status, and take away all the things they spent IP on. They're still basically resetting either way; just in this case, they won't lost the tens or hundreds of dollars they invested into the game they truly love.
