Apparently once you joined the seedier side of MLM (i.e. the pyramid and Ponzi scheme side), you get addicted to the easy money and you can't get out.
Kevin Trudeau apparently started cheating his way through life right after he finished high school, and quickly got into bank and credit card fraud.
Paul "ZeekRewards" Burks apparently operated multiple MLM businesses before shifting over to Ponzi scheme business model.
And this is hardly a Western practice, as apparently scammers are the same world over: it apparently is the only thing they know, once they had a taste of easy money.
Meet Yoshio Matsuura (松浦良夫), of Japan, and his link to at least two scams: Skybiz... and Interush.
