According to SocialToo's Jesse Stay, the scammers have figured out a way to exploit the "Like" button via JavaScript and are using it to force users to like the page, thus spreading it inadvertently through postings on Facebook walls.
The result is thousands of wall posts for a page entitled "Shocking! This girl killed herself after her dad posted this photo." Clicking the link enclosed spreads the worm further. Unfortunately, this is not the first time we've heard of such an exploit, but according to Facebook Search, a lot of people have been affected by this one.
Do not click any of these links or go to this Facebook Page. It will force you to like the page and spread the worm further. As far as we can tell though, the exploit doesn't compromise your account or steal your password. We've put an e-mail out to the Facebook team for more information.
