Do people on any of those candid camera shows get anything?

From funny prank shows like Jamie Kennedy Experiment down to serious things like To Catch a Predator.

Do people receive anything from these shows at all?

Don’t the ‘victims’ have to sign some sort of release for the networks to be able to use them in the show?

For example: Sometimes on JKX they offer fake work or some sort of interview. Do they get like 50 bucks for their trouble?

How about Punk’d? Do the ‘stars’ they prank get any royalties for being use?

And for to catch a predator, how in the hell do they get the guy’s permission to use his image on the show? Are there loopholes they use to get around that? Or are there special rules for ‘journalism’?

What other shows are there and do they get anything?
