There's actually a better way to stop sponsors that redirect to their own wm ID. Instead of leaving it up to the webmaster to find out if it's really their link code that they see, leave it up to NATS.
Someone clicks my link code. IP is logged and cookie is set (haven't checked if NATS does that, or what ever you do to track users). If that same user comes back within x seconds with another wm ID, bingo. We got a redirect. Can even check if it's an internal ID or another users ID.
If it's internal, then you got yourself a cheating sponsor.
If it's a different user, then you got yourself a cheating sponsor, rogue designer or someone that hacked your stuff (like what happened to another sponsor a year ago).
Damn, I write way too much. I've just painted my ceiling so I'll blame it on the pain fumes
