Hi, guys. You are right, MMM really looks like  a bit shady. Because the design is not great and the people, who write the posts here are speak english not so good. And me too)))) and I’m sorry for it. BUT…
I can explain it. The Mavrody, the founder of  project – is common guy. He is poor, he does not have anything (villas, cars, yacht…), he even has never been abroad. He does not want. He is NOT materialist. You even can take а look  at him, when he give an interviews, he clothes simple sport suit. I would like you understend russian and listen his https://www.youtube.com/watch?v=qXiG2dl4KhI He fights for idea!!!!  And so, the guy who does not have money can’t create good destined site! You have to understand it.
He believes that we (you, me, they..), common people, we can change the world. We  can be free from financial slavery, bankers who with the aid credits made us their eternal debtors. I believe and I want to be free.
MMM – it is pyramid. But you know, that any state has build on the principles of pyramid. And the country YOU live in!
