    AdWords and AdCenter (and nearly every other paid search engine) can see the traffic flows (their own and partners), and see whether that traffic converts – it can then grade it’s traffic based on it’s value.  Through Smart pricing and many other mechanisms, in addition to bad clicks, they can easily see bad aggregate flows.  Meanwhile, FB ditched it’s early conversion tracking platform beta, creating a situation where they have a much harder time grading, and therefore valuing and policing their clickstream data.  The “like” conversion path (that they can see) isn’t a sufficient barrier to be used as a click quality metric – an actual person pulling out their credit card and ordering, is.  FB, conversion tracking wasn’t just for our use.  :-)
