Traffic-trade scripts

[fever]

Im planing on trying to get as much of my visitors to one of my link-exchange-sites. The site I will link to is the kind of site that uses a script that works like I send 200 they send maybe 250...
So what I wonder is who of you that uses that kind of script. Anyone understood that...
