Take this with a grain of salt. The "company" has 400 likes. Not exactly GM leaving Facebook (and then quietly returning to Facebook).
If true, Facebook should really have anti-fraud measures in place for this kind of thing already, and if they don't, the size of the company in question has no relevance to that.
Obviously the news here is not the loss of business for Facebook, but the fact that a click scam was taking place (if true).
And the click scam, if true, will take away the only way for Facebook to monetize the product. Marketers are not stupid, things like this spread like wildfire.
