I think you're pretty mistaken in thinking any proof would be available or required. All these maids are typically paid in cash. Unless the person has bruises, or complains that they're not being allowed to leave---the police would ignore the situation. Compounding this effect is that most 'maids' are distant relatives in the western sense---being 3rd cousins or nieces through marriage to the hosting family. When push comes to shove, the host family just claims truthfully that they are all a single family, and the sleeping conditions of an adult who isn't being forced to do anything is really no ones business. --- As an edit. What I'm describing is the traditional lifestyle of West African maidservants. All maids are relatives, since no one trusts anyone who isn't related to them to live in their house. The world is a big place though. I wouldn't be surprised if maidservant lifestyles in Asian countries or Middle Eastern countries was much different. Middle Eastern countries even use foreign-born servants, something that'd be seen as the height of insanity in someplace like Ghana.
