That reply feels needlessly adversarial. I'm not claiming they "refuse to tell people", my point is that this isn't clearly documented in the public rules and, as far as I can tell, users aren't notified when it happens (nor is it something staff states proactively).

I only learned about it after I asked via a non-public channel, with evidence. Otherwise I wouldn't have known, and I suspect most users are unaware. What I cited in previous comment is also from a non-public conversations.

If I'm wrong and it's documented publicly in rules or users are notified when it happens to them, I'm happy to be corrected, link?
