Profanity Filter - make it optional
Give a toggle in settings. Have profanity filter on by default, but allow people to turn it off, so that they can see what people type in chat. The profanity filter randomly filters out normal words, killer and map names, without rhyme or reason, on and off. I've seen it filter 'Haddonmemes', 'Myers', 'Ormond', and 'Hawkins' before. Why? I don't know if what someone is saying to me is profanity in the first place, due to how overzealous I've seen the filter be. On top of that, people keep finding ways to get around the filter each and every time something gets censored, so it's pointless.
I'm not saying the filter should be removed, because people both want to be able to talk and not have to deal with another person saying whatever they want on the other end of their conversation, and I'm all here for that kind of hypocrisy and denial. Profanity, in a M-Rated game featuring gore, constant violence, and occult sacrifice with unrated online elements? Outrageous.
All jokes aside, for streamers and such trying to avoid the kind of speech that their platform prohibits, the filter makes a degree of sense, albeit being a piece of paper trying to block a flamethrower. But, that's not a reason why everyone else should not be allowed to turn off the profanity filter. Let's be honest - after playing a game that has not changed in any meaningful way (gameplay-wise) since its release tons of times, one finds that the only variety to the each match is in end game chat. Not being able to see half the messages makes the post-game experience worse.
