Not this Part II video, but Part I was mostly focused on Mr. Beast constantly running illegal lotteries targeting children.

Not choosing winners at random, preselecting winners from friends & family of his crew, making purchases a condition of entry into the contests, not clearly advertising that contests could be entered without purchase, suddenly changing contest rules minute-to-minute while live on stream, not fulfilling these frantic changes in contest promises in real time, having his crew forge his Mr. Beast signature on merch, etc.
