I happened to find one user's profile and it has the following words:
You is a piece of crap... piece of shit... Go fuck.
I flagged a post by this OP on two different sites. One site accepted my flag as being helpful and the other declined my flag saying
Offensive language is allowed in profiles, cf. Why is the f word still allowed in profiles?
I don't mean the f-word used to emphasize another word or your point as an intensifier. I mean those offensive and rude languages directed at you when you read it.
If you read Does the Be Nice policy require SE users to "be nice" to people who are not SE users (e.g. public figures)?, users are discussing be nice policy towards non-users of Stack Exchange. When those languages are directed at users of Stack Exchange who happen to read their profile, don't you think they should not be allowed?
