If I remember right, something like this was discussed a while back when posts where being made in code or some kind of foreign lingo. It was determined that is a n English speaking forum and all replies would be made in English. I would imagine that includes ebonics style too.??? or mocking of other nationalities etc.. But, I think jokes are OK
... if I were to sign up here as Laqueesha Jones and post in an ebonics style that was in some ways deliberately mocking of blacks, wouldn't that violate the TOS even if the majority of my posts were otherwise marginally acceptable?
