Let's talk Chat Restrictions

Let's talk about chat restrictions.

I have a friend who is constantly chat-restricted (and I admit I report him when he goes over the line) and he is quite toxic to say.

Then I saw people talking about how they mute their entire team and communicate with pings only, and don't even type a word.

That got me thinking: "If you can communicate with pinging only, you won't be using those messages that you get during the game." So what happens? They use those to flame anyways. My friend is a great example of this. He can ping objectives and even though he is restricted, he flames just as much as if he wasn't.

And for who plays Draft Pick, You've probably been there where we play a Draft Pick normal game, and then there is that one guy who is restricted and isn't talking at all. You say stuff to him and give him advice every minute or so, and then 3 minutes later he just writes that loooooooooooong flame message, only using 1 of their chat messages to flame as much as if they weren't restricted.

The only thing I feel is good is the All-Chat restriction.

TL;DR: Chat restrictions feel useless to me and it can be easily tricked by flaming what you want in a long chat message instead of in 3 shorter ones.

Any thoughts and oppinions would be appreciated.
