I remember submitting coupons on retailmenot and getting them erased. I actually remember contacting them to post coupons that could eventually help their end users and them informing me that they wouldn't post it because it's not an affiliate code and they wouldn't get paid.

As a user, I wasn't getting paid either just wanted to help out since the coupon I found was superior than anything they posted for that store at the time.

Is their mission to help users find deals or pad their affiliate revenue? If it was the latter, their reason they gave me would make sense.
