http://fakehospital.com/tour/join.php is just a redirect. but if you download the file with download manager, you can see the source code, and in the source code, there is this
Code:
<script>window.location = 'http://join.fakehospital.com/strack/MC4wLjIxLjM5LjAuMC4wLjAuMA/21:39/0/1/join';</script>
there is some nats code, that is hard coded on the file/page, and the nats code is not the one i used to visit the site. it is nats code of someone or something else, not mine or not the one i came to the site with ... cant explain it better cause of my engrish ...

maybe its all good, just some standart code and it dont affect the affiliates nats codes, just, everyone have to go through the page and through that nats code on that page ... sorry, cant explain better in english

once again, maybe its all good, i just will be more happy to know and expand my knowledge about nats
btw, two other guys, sitting on another places, have the same nats code hardcoded on the join.php file, so its nothing variable if i am right ...
