Ask HN: What is Facebook doing to combat pyramid schemers?

Lately I've been noticing exploitative characters post baits in popular groups. They don't disclose the details of the supposed part time job, but instead invite interested parties to private conversations, where it's easier to swindle the more likely victims. After they're uncovered, they delete the baiting post, part the group and block anyone that's onto them. All the proof of their scheme disappears, and there's nothing to report them for. Even if you can access their profile, they can only be reported for lying about their name, or using a personal profile as a business (which isn't really the case).
