Deleted accounts joining OC?

You may not be able to see as the quality is small and poor, but the picture on the left shows a lot of '#'sDEL' joining OC. Of course, any account with a username like that is a deleted account, and usually noobs like those accounts get deleted for not have been online for so long. However, this gives the question- How are they joining OC? Well, no one knows. Some say they're stardoll staff, some say it's Mette, some say it's Robin, some are even saying it's the 2012 of stardoll o.e

Personally, I don't think it's anything to worry about x'D
