If I mute someone will it prevent them from appearing at the top of my feed?

Yes, i did that with a very provocative pfp....i then had to block them later for other reasons

Glad Muting works. Does it work for both sides though? Will muting them prevent you from appearing on their top feed?

Yes but not on top of their feed. I mean you won't see them on your photo feed but they might still see you on theirs.

I bet I was one of 'em🤓

Idk, do you like my avi?

I usually block. Muting isn’t satisfying

I am not sure if it does
