Whilst its sad that you cant use a legitimate name for your guild, you already know the policy exists to prevent muppets from naming guilds like they do characters i.e.
Me personally, id like to see them perma ban anyone with a stupid name, having already seen plenty of Darth ****** type names in the various Betas.
I agree, however, this has nothing to do with this post. The naming changed from allowing 3 of the same letter to only 2 when creating a guild. These annoying example were already impossible.
