This actually hasn’t been true for several patches now. The slur filter is no longer hard-coded, but instead is customizable on an instance-to-instance basis. This change sure doesn’t stop people from complaining about the (nonexistent) “hard-coded slur filter” though!
Yup! It’s what finally made me stop watching twitch (embarrassing, I know, I’m more of a gamer than I like to admit). Minutes of unskippable ads, way too often, and no adblocker could get rid of them. The best I could find was a twitch redirect that would block the ad, but it couldn’t give you the content back, so when the ads happened the stream would just go dark until they were over. I decided enough was enough and I haven’t gone on twitch since. I’m mentally preparing to do the same with youtube if and when they succeed in breaking adblockers. Which is going to absolutely suck, I watch a lot of youtube, but maybe it’ll actually be a good thing and I’ll be on the internet less.
