I'm going to find out a way to automatically hide comments referencing "musk". You can't even read about a 3Blue1Brown video without people somehow making it about him. Every thread, every day, it's just people talking about Elon Musk.
The hard part from there is design decisions. Do you just have that comment disappear, or fade like a downvoted comment? if it disappears do you remove the entire thread? is a contextless match adequate? (say, someone was talking about deoderant?)
