My favourite example of this was seeing a popular gambling streamer who had a permanent overlay reading "DO NOT GAMBLE, YOU WILL LOSE", but still raked in sponsorships from gambling sites regardless. Maybe the overlay helped him sleep at night but the sites know that wasn't actually going to deter anyone.

Then there's the shadier casinos that provide fake balances to streamers so they're never at risk of going bust, and can keep perpetually hitting the big jackpots that entice the audience...
