Xplicit

So this this bullshit or what?

Most seem to work like this:

1 - Signup
2 - Complete some "offer" from one of their sponsors
3 - Get -X- ammout of friends to do the same.

I run some non-adult websites with 10k+ hits per day that I could easily tos a banner on and refer some people. But my question is, are these companies legit?

Has anyone gotton free shit from doing this? If so, point me in the right direction.
