Poat to Social Networks

I need different and unique ip address to come and visit the website. They also need to be ACTIVE in the website. The website is helpful to people because it has different PTC programs and different ways to get coupons. THe best traffic is from the United States. Also, I just want people to post the website to their network (facebook, myspace, twitter, etc.) I also want proof of the website being posted. I will not pay unless the visitors are active. Also, please put down in PM "MCP" because this will let me know that you read and understand the project
