Of course Facebook knows that they are running employment ads. They don't know _which_ ads are employment ads, because they are not paying anyone to look at the ILLEGAL advertisements they know that they are running.

Yep. Nothing can be done. We have to wait for artificial intelligence to save the day. It would simply cut into profits too much to follow the law.
