I put the name Zazz Tomar, and before that, Zo Husk, but they were both classed as a name that already has a title in it, I've been waiting a while for them to be accepted, and there's no title in either of them for what I can see, why won't it let me?
That is actually the default rejection message when the person declining a handle is too lazy to fill in the real reason. In most cases this is because the name is of an existing character in another universe or somebody notable enough to have a Wikipedia entry. This may also be because a person has an existing account already or shares a connection with a player that does. I don't currently see a pending request from you, but I just made sure both handles won't be automatically blocked, so give it another try.
