CPA deals are not good for some programs rev share is the better model. More importantly Cpays in itself has questionable ethical standards of a wild beast. The program may work fine for some. Not sure what criteria cpays uses on who to jerk around or not, but they do screw people over such as myself.
Whether or not you choose to support them is a personal choice. From my own experience I would not. Perhaps do a search for Cpays on CAP to help you make up your mind.
