Not news...
I have seen a few of these 'racy' images previously.
Incidentally, twitter seems to be off again right now (5pm BST)
A Twitter spam campaign launched over Thursday night has seen many users of the micro-blogging site gaining new followers with racy profile images, inviting prospective marks to connect via MSN.

This has been a vector on several other "social" sites, including those involving class mates, year books, waste book, ya hoo, and more "dating" sites than you could shake a stick at.
Sometimes I can't believe I am paid to look for these things and report them.

Me: "No, not yet."
Boss: "Well look harder, dammit!"
I love my life. :)
