I've been stealthily permabanned from that sub. No warning, no second chance, no reasoning, nothing. Just checked, am still not allowed to interact with them and it's been almost 3 years now.
Here's what happened: Someone came with a post about Vivec, a demigod that wished to break beyond the duality of things, so they ran away with the LGBT interpretation of it. This caused them to neutralise every single pronoun in a rather cramped fashion, something I had literally never seen before and only like twice after. (he -> hir, stuff like that... or was it him -> hir?)
Either way, I asked calmly but directly what it was about, people replied with similar calmness and confusion. When returning a bit later, turned out my comment and all underneath got removed, and I was apparently not welcome anymore.
To this very day.
