Clickbank sounds very unpleasant with their hop system, hopefully they don't go greedy on our poor affiliate who worked their ass off.
Hops can be false, but sales stats are always correct ! If you see 1000 hops, it does not mean that you actually got them .. If you have 0 sales, then you have 0 .. that's all ! No need to start crying about it - just move on and work harder. We can find a lot of peoples doing well with CB, so - choice is up to you
