Unfollow Friday: Put Britney Spears at the top of your Unfollow list

The Twitter game to gather up as many followers as you can has already reached its epic proportion -- the battle royale between Ashton Kutcher (@aplusk) and CNN (@cnnbrk) to reach 1 million sheep -- so now it's time for people to start getting selective. So forget Follow Friday (for the uninitiated: the smarmy practice of tweeting #followfriday and a bunch of names to try to court favor and try to drum up new followers). Now there's UnFollow Friday.

And well there should be. Tops on the list: @britneyspears.

The account, which is supposedly her own actual account, now has about 1.2 million followers and follows back 377,000. But according to pages leaked from a hacked page of a Twitter administrator, Brit is actually being blocked by more than 3,000 people. So take that Brit.

Also according to the documents, pop star Lily Allan (@lilyroseallan) is blocked by 184 users -- and she is blocking, you guessed it, Perez Hilton (@PerezHilton). And who wouldn't?
