Twitter has responded rapidly to shut down a new worm, which spread vulgar messages from many affected users' accounts saying they err.. were fond of goats.

Some high profile Twitter users, including Robert Scoble, fell foul of the attack. Of course, having such popular Twitter users affected accelerated the spread of the message.

The messages read (look away now if you're of a nervous disposition):

i love anal sex with goats

Users found their accounts were posting the message of goat romance after they clicked on links reading:

WTF: <link>

Clicking on the WTF link would take you to a webpage which contained some trivial code which used a CSRF (cross-site request forgery) technique to automatically post from the visitor's Twitter account.
