Why don't you include their links so we can see what your talking about?
Most of these don't have websites or links. they just post on FaceBook groups. "Bitcoin earners" group is full of them. When asked, they either avoid the question or give you some excuse. they always play the same song. Its like they are one person, or they all copying from the same book 
Their most common response is: "It seems you don't know about bitcoin and bitcoin mining". especially when I ask why I need bitcoins in my account to mine for bitcoins.
One of them sent me this link https://tradewayopx.com/ when i told her I don't have bitcoins, I need to buy some. The site has 0 useful information. They supposed to be into binary options but they show no proof of that. Fake address and fake phone numbers.
