A stricter chat filter could solve the problems with chat toxicity

Before I begin, I would like to state that this is only a theory, I have not done any tests whatsoever.

With the current chat filter, anybody could just turn it off, my idea is that if everyone was forced to use it, people would get a better understanding of how their teammates recieve what you say. Even if it is forced on, everyone will just dodge the filter by using variants like "fuk" or "fk" and somehow even "fucked." In order of strictness added, I will show you my idea options. I'm doing this because we may or may not need to be very strict because I didn't test any of these. (All of these will require the chat filter to be on)

1. Censor all forms of variants.
2. (All of the above) + Completely deny any chat message that contains a censored word.
3. (All of the above) + Allow teammates to vote gag a toxic ally.

In conclusion, the chat filter isn't all that helpful, and making it stricter will surely stop people from being toxic in chat. In theory, option 3 could literally fix chat toxicity, but it needs testing. As we all know, the mute button alone can't end the toxicity.
