I'm not arguing that it's good, only that it's not as exploitative as the parent made it to be.

Also, until now, the most questionable thing would be the 100 days in a circle one, and the reward is $500k. I think most people, even if not in dire need, would happily go and do that. Here in the comments you already see examples of that.

And, most importantly, I don't see the "coercion" anywhere. Most of the people participating are subscribers to him, he's not just searching for poor people out of the street.
