I personally wouldn’t touch anything even remotely associated with Cpays. When I started my site I negociated a deal with that lot and it was a disaster unlike any other! I had my affiliate mgr there changing my ability to read full stats and even went as far as to ask me for my password so they could look into it!
I’m no rookie to this business by far and have dealt with many aff mgr’s and for most part all have been great and none ever have asked such things. For me, William Hill is off the books and it is not relevant to me what changes they make in the future.
I’ll never touch them or allow for promoting of any of thier sites on my sites. Sorry, but it just plain fact.
