That’s the only sub I was ever banned from, and I was banned twice. First time the mod said my comment didn’t fit my history and asked if it was a joke. I was unbanned when I replied it was, indeed, a joke. Second time was more or less the same thing. Banned for trolling.
I used to comment on many subs, and I would sometimes write something sarcastically without the /s. Just depended on my mood in the moment. I unsubbed because I knew there was no way I wouldn’t just break the rule again. Also, I didn’t want to read a sub I was banned on because I would forget and likely waste my time composing a comment that would be rejected.
