There are standards for game shows, giveaways, sweepstakes, lotteries, etc. No idea of BS&P applies to Youtube content, but regulations for others should be adhered to. If that former employee is to be believed, and some of the examples raise questions in my head, I'd be more concerned legally than about being cancelled. And the channel should be held to account if they aren't following regulations and guidelines, as it's highly exploitative to an audience mostly comprised of the easiest demographic to exploit. How much stock you put into the voice of a former employee is debatable of course as it ,can easily be seen as an axe to grind or someone chasing their own clout.
