Here are my thoughts...
1. Do you accept payment for a "review" ? Maybe to keep it clean we should do an independent poll (not on GFY).
2. If this is not an ongoing test -- I don't see the use. I'm going to assume that most shavers are not on all the time -- and not on for all affiliates -- especially in the first week or so of sending traffic. Lets get some professional input from real programers that have coded shavers...
3. Are you only testing trial programs?
4. Why do you care? If you do care about X program -- why not test it yourself... Or is your goal to make a suspected-dishonest program honest again?
5. I think using a bot is a bad idea -- I'm sure you can spare a 100 crap hits for a test...
6. What if the sponsor claims that somebody signed up with Browser X that did not track cookie Z correctly... You need to make sure that the testers have cookies turned on, etc. for the audit to be accurate...
7. Try to get testers with different ISP's and different countries... A good way to shave would be to shave by ISP or by country...
I think it's a good idea -- but like Exxxotica I'm pretty lazy -- maybe I'll help out in round #2 if it's for a program that I think is worth reviewing

I have some suggestions but I don't want to do anything out of taste in public LOL...
Maybe we should target affiliates' accounts that suspect shaving... Like if webmaster XYZ is converting like 1:3000 and he's going to drop the program anyway because it sucks -- this would be a "more perfect" opportunity to crank up our shave test... For example I tested some traffic on Big Players -- I made $50 off 1 trial right away (duh) -- but after about more hits I didn't make any more sales... great opportunity to do some testing at that point -- not like I'm going to keep using the program anyway.
