I just asked: Muting would make it so you couldn't see their part in conversations, which is a problem for their non-toxic content showing up in conversations that you're a part of.

What do you do when someone somewhat important in your industry puts out 20% abusive/toxic content (and that 20% is probably 90% of their engagement)? If you ban them you create drama, if you mute them you're still cutting yourself out of potentially important non-toxic conversations.

But when you don't ban/mute them twitter seems to want to constantly show you their hottest hottakes-- the very reason that you're not following them. (I'm not even sure if muting is enough to prevent the recommendations).
