I like the point made about complaining only if you don't violate all the other rules. This person wanted information, not morals.
As many of you well know, I have pointed out that the majority of what goes on on coupon connection violates the rules. They are violated any time there is an exchange of value. Interestingly, in this regard, I just saw some new wording from NWA on a coupon to the effect that rules were broken and coupon was void if any form of consideration was involved whatsover.
My point? let that guy do what he/she wants, you do what you want, let the chips for both fall where they may, offer helpful info if you like, or don't if it offends you. We are all sinners here (with incredibly rare exception) so pontificating about anyone elses moral choices is rather weak. This isn't drunk driving or sexual harassment we are talking about...
