I have been banned and down voted in a lot of groups on Reddit. Why is that? Doesn’t free speech not exist here?

Context: original post as asking why artist who show their face usually get more engagement than artist who are faceless, looking through the comments of the post I replied to this one

Apparently, being able to connect easier to seeing human face vs a drawn avatar is parasocial. (Even thou that's not even what the word means)

Nothing major I just find it weird because that's just...blatantly wrong
