Blacklists not only broken but do not do enough

I made this report 5 MONTHS ago, blacklists SHOULD block those players both in CHAT and in GAME, I shouldn’t have to fight a guy that I blacklisted because he is a toxic abusive pos.
Yet, Every match their chat is grayed out, but not blocked. so they can see my chat and I can see theirs.
It blows my mind that a “team based” game has no communication and chat never works.

(That is today)
Yes I reported it to GM’s Yes I reported it in replays. Yes I reported it in game.
Still an issue.
Made another 7 months ago, with more proof and pics.
