Facebook's Crackdown on Scammers Prompts Them to Move to Twitter

Internet scammers finding it harder to get away with the same old scheme on Facebook may be turning to easier and greener pastures on Twitter.

Experts at security firms such as Sophos say they've seen the social network's security teams recently crack down on the "watch-this-video, count-your-visitors, see-whose-stalking-you" scams.

That slowdown, if it lasts, is good for Facebook users. But Chester Wisniewski, senior security adviser for Sophos' threat-research team, suggests it could forecast a coming shift.
