Edit: Seems like the Mod-Logs are public, so it’s not ‚secretly‘. My preferred mobile app doesn’t show this and for me the post just disappeared from my history.
Anyway, the breach of rule I allegedly did is obviously an excuse to block inconvenient opinions as it’s not at all related.
I can't speak for others, but I've had several posts censored. I even got demodded on a sub I created (/c/intelligence). In all instances, I never received a warning, notification, message or anything. My posts were just gone, my mod privs just removed without ANY contact from who did it or why.
