Where anyone comes up with a figure like 30% from is beyond me to be honest. If we saw that the average site owner with a reseller program was only paying resellers on an average of 30% of his incoming sales, we'd look at just where the traffic was coming from for other reasons as well.
We offer more than one type of tracking, depending on the coding, and quite frankly, using more than the standard doesn't really increase joins. Our new join system, which is in beta right now, will also add increased functionality and tracking for the site owners, and we are working on an update of the reseller programming (internally) that will enable resellers to track where their joins are coming from -- something you've all asked for and we've just not been able to implement without finishing the new join setup first.
Just one more case of someone playing Chicken Little instead of analyzing their own traffic's weaknesses and reacting accordingly.
You guys know if you have questions about anything in our system or how we do things, all you have to do is ask. I'm not very technical but I do know where to find the answers
