This is a regular scam method for them... Ordinarily, if you look at their cooked-up testimony, you will understand that those stories are too good to be true.
Old and regular trick but still sieves some victims.
There are always those greedy and uninformed ones amongst the crowd, popping there heads up in search of opportunities to offer no service, do no work and yet wants to reap huge.
There desire to not to do any work has been there trap and until they realise what failed step it is to not want to do no work and still determined to earn good money, they might as well be seeing hope even after been scammed severally.
What people should do is seek information, ask questions when your approached with deals, see some risk as well as value your money and only when your sure should you give it a try. Don't let greed lead you.
