I can’t give you any advice but I imagine you have already determined you can’t get to him for any legal shenanigans. I know a MLM scammer who went to the pen for a few years in a real estate fraud. If he is vulnerable financially then that is where to hit him.
Especially if he is one of these “Christians” who think they can claim what is ‘rightfully theirs’. I absolutely hate cults and I detest the people who use religion to make their ‘residual income’.
