I visited this subreddit once, it popped up when I made a search for a TV show I was watching. I made one comment where I responded to someone asking if anyone viewing the thread was asexual. I said "I'm ace", and was banned an hour later, with a note calling me a degenerate. So, I looked at the sub more thoroughly and concluded it must have been a parody, and I just didn't know what it was a parody of, so I didn't get the joke.
I'm disheartened to learn that it was serious.
