Disallowing usernames


Well-known member
Do you disallow any usernames? Most softwares (by default) wont let a member register with the username "admin" or "moderator," Have you added any additional usernames to this list? If so, why?

Would you allow a username with an obscene word or profanity?
I do. I disallow my own nicknames from other places, just to avoid people "impersonating me" or confusing others by doing that. Selfish, probably, but I just don't like people "being me" on my site. One of my nicknames gets often chosen I found, so the chance of it happening is rather real. Apart from that, we have a user admin and I think we disallow "mod", "moderator", "God", "Goddess" also.
