A solid rule of thumb for people in moderated spaces online: if anyone ever starts whining that they got banned, and ALL THEY DID IS [innocuous thing], no they didn’t.
there was a time when I was the victim of poor moderation, but they actually made it fairly easy for me to determine why I'd been banned - i hadn't done anything
the forum expected new users to introduce themselves in a timely manner, but just after finishing signup i was called away for something that took enough time that they decided to ban me preemptively.
