Sorry to read of your current problem with a sponsor samebb.

I fully understand the importance of a sponsor's TS and their right to fully protect their brand and property(ies). If I was running a program, I certainly would have had the professional courtesy to explain, even via form email, the whys and wherefores for the violation/cancel.

It appears though that some sponsors think they are only doing a favor to affiliates, seeing no need to explain why an agreement was canceled. There was another thread where CorbinFisher plans on ending their agreement with hundreds of webmasters.

As a sidenote, personally, I avoid sponsors that use cascade billing, my feeling that many sales would never be accredited.
