Q: Where does the visits come from ?
A: We have some affiliated websites that we pay for their exit traffic. All the visits come from exit traffic. Most of the sites and the visitors are Brazilian and South American (nearly all of them speak English regularly).

For boosting trades it could be good. I bet they click like hell
as long as itīs free.
