I agree with you. If a couple is advertising for both of them to get laid, it would be better to post pics of both of them so that people have a better idea of what they are getting! Just seems logical to me!
My worry has always been that the female is being used as 'bait' -
We use to have pictures of just me up, although we now have a pic of Mr NC up. The reason Mr NC use to put the pics of just me up was because he likes showing me off. I think this may be quite a common reason.
We agree 100% with you legobabe.
We like to see both parties on webcam before we meet. That way we know they are genuine. So far we have had no problems.
