There's 2 different issues here:

1: The way the caribbean flavor cash program was set up.
I think John's reply was clear on this. The "hide join" option can't be used if the program is paying on joins. It is however important that affiliates realize that a program can pay on rebills and not joins. So the real problem here was the way caribbean flavor cash presented itself. They presented themselves as a 50% revshare program when in reality they weren't paying 50%, but only 50% on rebills and not joins.

2. Other potential ways to shave (not necessarily limited to NATS) and how software like NATS can detect these. To know if the scenarios posted here are possible, we'll need to wait until John is back.

edit: I see he's back.
