Today Facebook and Washington state's Attorney General Rob McKenna filed suits against Delaware-based Adscend Media LLC for violating its alleged clickjacking the CAN-SPAM Act and Washington's Commercial Electronic Mail Act and Consumer Protection Act. The company, which offers "affiliate marketing, content monetization, and virtual rewards services," allegedly brought in $20 million a year via the deceptive clickjacking or lifejacking processes.

You've probably noticed messages on Facebook and other social networks that are scammy enough that you can tell they're not from your uncle or grandmother. The posts promise to show some shocking or salacious video footage, and when clicked, load pages that try to trick Facebook users into clicking deceptive links and 'Like' buttons (hence, the "likejacking" term). The malicious post is then driven back into Facebook via that user's unsuspecting friends and family. "Most people would not recognize that this is not a Facebook product. That's why we don't like these," Facebook General Counsel Ted Ullyot said. While this practice of likejacking isn't new, their social nature makes them increasingly effective; Ullyot calls it a "constant arms battle."
