The upsales should not be on any affiliate traffic. This has been fixed last year. From what I see, It seems that there's a bug. It will be fixed monday at the same time that I will wipe some ass...
We are currently working on a system that will let you controle all the upsales and get pay on all of them. You'll be able to controle if you want them or not, add exit and a lot more amazing features... it should be ready in January.
If anyone need to talk about it, hit me up on icq 30975654
