This is a false allegation and you know it. He gave a lot of money to friends, and that was always known. He lied to a lot of people and probably tricked a number of idiot adults. If you say kids used credit cards to spend money online then that was 100% on their parents because banks do not give credit cards to kids. Everyone is a term that means everyone. That would be found guilty in adefemation suit. He would be morally/ethically wrong to sue someone like you for saying it, but he should legally win that every time.
