Memmy on iOS has filtering under settings. Haven’t tried it yet but presumably typing in “hexbear” would not only filter out comments/posts from the instance, but also comments/posts about it from other places. Never have to deal with any of the drama again. Also filter out anything else you don’t want to see.

low resolution and doesn’t have subtitles but could be downloaded and combined with subs from elsewhere probably
