Perma-chat ban will never work, and here's why:
Let me ask you this: Why do you have to be toxic to your teammates? Imho, I'm very sure it is just to:
- attempting to piss off your teammates for their mistakes.
- taunt unnecessarily.
- just plain angry or having a bad day, & you decided to take it all out on your own teammates.
Now let's say you got perma-chat, and you think you're all safe from the punishment system now, aye? Well guess what? You're not.
Another game doesn't go your way, so you got frustrated all over again, and let's be real, no one is dumb enough to still continue using the chat system when no one's reading it. Yeah, you would think that throwing stuffs around or shouting at the computer screen may be ironically embarrassing & bad mannered, assuming you're living with your family or friends. So what do you do as a last resort? The answer is:
#AFK or Intentionally Feed
You heard me, this is definitely what you would do to express your frustration. Any excuses you have in mind thinking my statement is dumb, keep reading the bolded text in my last paragraph. So for the last time, just take the punishment you have right now, be it a chat restriction, 14 days suspension or especially a permaban.
