I have always been very sceptical about charge backs – I think that it is a little bit too easy for a casino etc. to cut affiliate earnings at the end of the month.
If I experience a charge back, I always ask the casino etc. for some clarifying informartion, which I usually receive.
I have asked about this problem before here at CAP, but there has not been much interest about it. Guess it’s not a problem for most affiliates?
