1. Facebook have just come out with an entire release about what data is and is not tracked when you're not on their site[1]. 2. Armchair developers always throw out things like this: "A few if-else statements would remove most of them and would provide at least a temporary solution.". Sure, you could do a keyword search for "pills" and delete all of those ads. How many legitimate ads will you take down in the process? How many extra support requests will they have to deal with because of the change? How long until the spammers change the wording ever so slightly to defeat Facebook s naive workaround? 3. Facebook doesn't directly give data to advertisers, that's what Zuckerberg was saying, and OP acknowledges as much. The fact that advertisers can infer data about users by using the system is a feature, not a bug. The very fact that you can do targeted advertising is of course going to leak some data about users to advertisers, it's not Zuckerberg's job to explicitly state that.
