Chat filter is broken. Players willingly turn off chat filter, then report players for chat that they willingly subject themselves to. It's not an excuse to be toxic but it is fundamentally flawed.
Players should only be restricted if they manipulate chat to bypass the filter, and are reported. Otherwise how can any chat ban be justified. You willingly turned off your filter and that action may as well say "im ok with seeing anything in the chat"
If you have filter disabled, any chat related report should be instantly thrown out.
