I've seen white cheaters do it too. But yeah, if they're on Maury, they should know it's a set up. But then again, if they were smart, they wouldn't have agreed to go on Maury.
Maury, in my opinion, is actually worse than Jerry Springer. Maury pretends he's going to "help" you, Jerry is upfront about how he's just exploiting your "situation" (aka idiocy) for entertainment.
