I'm not aware of much like this besides mechanical turk. In any case, no one is forcing people to work, it's just an option they otherwise wouldn't have. You can argue their lives won't be any better with it, but I can't see how they would be worse. You make it sound like they are going to be rounded up by slave drivers, and otherwise would be pretty well off.

The worst case would be existing industries that are currently bound by minimum wage and working laws, that then find ways around the regulations. But new industries that didn't exist before mostly add new jobs, not replace existing ones with worse ones.
