This doesn't work though. I was banned there without as much as a single-line explanation after 10+ years of being a normal rule-abiding user which didn't change even up to that point. Maximum stuff they might not like I did is visiting through a proxy due to my country's circumstances. Right after that I tried appeals daily nearly for a week with no reaction whatsoever. So I just deleted my acc, less value for them is better.

Thank you for that. Yes I did fill out that form. I only realised the shadow ban several months after it was implemented. The clues were not being able to update user handle, server error thrown when accessing profile, content suppression. So it's serverwide. I've decided to move on. I closed my account.
