Why do they take part??

Genuine question- given the very low success rate of successful matches and the very high / unavoidable level of absolute drama, why do people still sign up to take part in MAFS?

I’m here popcorn in hand to watch it all, but I don’t understand how so many people who seem genuinely nice and good still sign up?

Surely they wouldn’t do this for another experiment where past experiments have more often resulted in total car crashes??
