MrBeast is the most popular and successful YouTuber to date. He holds contests that I feel encourage people to do stupid things that he finds funny, but insult the person doing them.

I also feel like people look up to him as some sort of Godfather-like figure where they both seek his approval and fear his wrath.

Regardless, he is very rich and he makes no bones about showing off how rich he is. I would not consider him a good influence for children.
