I thought about these sites who are selling traffic, 10000 visitors for a couple of 100$. I belive they have lots of small sites on free hosting companies, who like most small sites gets a few visits a day. But they direct the visitors to the site who have bought the service.

Anyways to produce a large number of sites there must be some programs involved. First to make or copy a large number of sites and then to make accounts for them on the free host. A computer must be able to do that all the way to the security code that most signup sites use wich the human have to write.
So do you know wich programs that could be used, or how it's done if I'm wrong.
