Meta has a long history of breaking the law. I have no doubts Meta will have access to the personal details once you've "verified your age". They'll know WHO you are, as accurately as possible. Can you imagine how much that it worth to Meta, history's largest harvester of personal data? A whole lot more than $2B.

Now, based on their ruthless disregard for the law, do you think they're just going to use it to sell your ads?
