Not sure if it's been patched or not, but there was a bug where one (not sure if it has to be a new account or if it works with older ones) could change their name to any name, even taken ones. I don't know a lot of details about it, but I've seen someone do it. I could dig up a video on it I saw if people are interested enough. It shouldn't be too difficult to find on Youtube anyway. Zezima is a Pmod as far as I remember, and the glitch doesn't add crowns next to ones name.
