We have one rather persistant user who keeps adding him/herself as 'Admin Team' or 'Admin' or 'Moderator' or using words of our site URL. Where can I locate the IP of this user? I will then be able to at least ban that IP from joining again. More elegantly, a way to limit the nickname allowable words would be more ideal but this only seems possible via a third-party module... it seems like it should be a basic core component.
