I tried them for about a month and generated many referral sign ups but after that when i was trying to contact them they won't even reply. Then I tried using other email to contact them and pretended as a my best friend and ask about the reason why they are not responding on my emails and they just simply say that I am a scammer.
I am so sad, after i made so many referrals they treated me as scammer. Or they just simply avoiding to pay my referral earnings....
But if you like them then try them and try wasting some of your time
