This was cited by the reddit admins as the reason they have just banned my account, instantly for this single thing, I've never had any other problems on the account.
It was a joke. A funny one at that.
It is absurd because "nonce" is barely a bad word. Equivalent to "dummy" or "shite".
Reddit is so shit.
EDIT: My appeal just got rejected. Landlords are officially an immutable identity akin to lgbt people and gender according to reddit. Also "nonce" being equivalent to "wanker" is apparently meaningless to them.
I'm quite annoyed.
How is it even an insult to point out the admins are all american and wouldn't know our brit slang? Nonce is incredibly British and barely known elsewhere.
Calling someone an American is a pretty big burn
