[pessimizer]

This will always be an issue, but we don't run around shutting down and suing Monster.com because they allowed ads for unsafe construction jobs or financial firms that engaged in illegal activity.

You want to encourage this stuff to all run through the same site, and to give police carte blanche to poke around that site wherever they want (as long as their customers civil liberties are preserved, due process, etc.). A site that would keep good records (and inform their customers what records would be kept.) That sort of thing.

Instead, it just got driven back underground. Nobody is checking IDs underground.
