I think you're missing the point, it is impossible to be able to prove anything, one way or another, if they refuse to give affiliates data that pretty much every other affiliate program gives without question. People are asking for transparency, videoslots refuse. That is going to raise suspicions, regardless of how much trust is there. How many programs do you promote that don't show deposits? For me, its one, videoslots. From the figures that have been posted recently over there, the deductions are huge and I won't be pushing them much at all because of that, and if I'm being honest, I can see why they kept them a secret! I can also see why super affiliates don't push them that much, as, unless they are on a bespoke deal, it wouldn't be worth it. Be honest, did you realise so much of the net revenue was removed when you first started promoting them, as it doesn't state figures in the T&C's and the affiliate managers wouldn't tell you either.
I had already stopped pushing them before this happened, quite some time ago in fact, I still get odd customers signing up but the fact is I've made nothing from around 100 customers, I wouldn't expect to make too much from such a small amount, but would certainly expect it to be higher than it is. Thats something that I see repeated time and time again by other, much larger affiliates. It doesn't mean they are dodgy, just that the fees they charge are much higher than anywhere else. Unfortunately, thats something you can't possibly know until you have promoted them for a while, as they refuse to tell you what the fees are.
