10% of Meta's revenue was from AI backed scams on users, that's $16 billion. They have no intent to stop it, merely to not get caught and fined.
edit: by well designed I mean that they put the lies in a chart or something. The lies themselves may be quite obvious to spot, like saying that 86% of marriages in Spain end in divorces (when the reality is hard to measure but more likely about 50%). Still, Facebook users don't seem to spot them (or maybe the ones spotting them don't comment?).
