Guys, a permanent chatrestriction won't work
I've seen quite alot of posts about this recently. "Don't permaban, just remove their ability to chat".
This WON'T WORK. Riot did this before, I were around at that time, and it didn't help. Instead of flaming, they would just troll the games instead.
Learn how to fucking behave. So tired or people that tries to find other sorts of punishments. Just BEHAVE, and you WON'T get punished. It isn't that hard.
