I take it you are talking about the infamous TrafficSwarm.com? Avoid it. I used to use it for a site i use to run a few years back. Used to get quite a bit of traffic, but they would close the window as soon as it popped up. Why would they want to look at a site that has popped up in a new window and is of no interest to them? At first i thought "Wow, so many hits!", but my logs were saying that over 95% of the traffic from TrafficSwarm.com were leaving my site in under 5 seconds. Brilliant!
Like most of these type of sites, TS is no different. You will just be wasting your time.
