What's a legit interest? Well, I can tell you what it *isn't*. Facebook claimed that they *had* to spy on you, even if you opted out by laboriously clicking through one of their dickovers or by transmitting a GPC signal to their servers, because you had *also* clicked through their terms of service, which say, "Facebook is going to spy on you with every hour that god sends, from asshole to appetite, abandon hope all ye who enter here" (a direct quote).
