The video author posted this comment under the video which goes over his main claims:
“Claims I provide evidence for in this video:
Many MrBeast videos are fake, contests are unfairly rigged, and contestants are often undisclosed friends and family of MrBeast employees, or employees themselves.
MrBeast has run multiple illegal lotteries targeting children. (I estimate they profited over $10,000,000 from these lotteries)
MrBeast knowingly sold merch with fake autographs while claiming on his website that “The autographed piece is genuine”. (fraud imo)
