Just more thoughts:
All of your customers should take issue with this. Scenario: You could build a web site that says:
These are the best website designers in the world and they use our stuff... and you pick who is on that list.
Great for those few.
Then you bill them to be listed.
Great for you.
See how bad this can go? So stop the contest thing... remove it. Let us buy your stuff and not get into another level of crap.
