100keywords. ( Traffic )

[[xtm]]

Hi there, I was looking around the net and i stumbled across a site the said it can Guarantee a certain amount of visits to any site per day,

I was just wondering if this was a likely scam or if any 1 else had used them. Or if there is better places out there that offer this sort of service?
The site is listed below.
