It may be difficult to become a billionaire running ONLY scams, but most billionaires engage in a few dubious activities here and there.
I looked up Johan's history and he really does not want people knowing how he earns his money, so we will never know.
I said this many times before and i will say it again. There is not a single company whose stock price has increased during Johan's tenure. I'm not going to buy TMPS just because Johan is the owner.
