It's mere coincidence, but your spelling "Casablanca" as two words (Casa Blanca) put into my mind that the literal translation of that place is "white house" (two words, natch). 
To your point, yes, Facebook knows user data trafficking (gambling) goes on as well as the stakes of such trafficking. Facebook is the gatherer and ostensible guardians of such data, but they directly profit from such trafficking. Very likely their "interest" in user data security is pretense.
EDIT: recast second paragraph to more clearly convey intended meaning.
