I recently saw a user with a user name that I thought could be a little offensive. I searched on Meta and could find only some references on a policy for using web addresses as/in user names. Nothing related to offensive or invalid words. Is there such a list/specification? If not, will there ever be? And, probably the most important aspect: am I the only one who thinks this is not OK?
Here's a snapshot of the aforementioned user. The post is here (EDIT: The name of the user was meanwhile changed).
