That was Reddit's choice. Blocking used to be a mute function. Then in 2021 or so they changed it to "you can't participate in a conservation I'm having at any point in the chain." Everyone said it was a bad idea and one post even demonstrated how easy it'd be to abuse such a function:https://www.reddit.com/r/TheoryOfReddit/comments/sdcsx3/test...

Awful idea.

All that said: Twitter stule threads are much more ephemeral. So a block isn't as impactful there.
