Twitter following weirdness

This is very odd.  Just got a message I am being followed on Twitter by Serenity White (Serenity6176) at http://twitter.com/Serenity6176.  Visit the page, mouseover the ‘following’ icons.  Notice anything? Yep, all Elmer.  Is it some weird fetish (we won’t even consider Elmer porn) or a bot that searches out Elmers on Twitter?  Normally I would just block this sort of thing, but this intrigues me (enough to actually right a blog post) so I’m going to keep an eye on it and see if anything happens.
