Owlcatraz Name flagged for change

Hi,

I've had a Druid on Lordaeron for about 4 years, but haven't played it for over a year. Today I was going to play it and found out the name was flagged to be changed. The name that was flagged is Owlcatraz, which a lot of people liked since it combines Owl and Cat into the name. Also the name is a play off the famous prison Alcatraz. My question is why can't I have this name for my Druid? I really liked the name and it couldn't possibly be offensive to anyone.

Edit: It must have been a bug because I was able to just rename him the same name. Glad that solved itself!

Thanks
