I don't know the answer, but would it help?: I mean, endusers visit and trust Godaddy, not Afternic. Afternic is Godaddy's reseller face imo. I don't like this situation, this allows Godaddy to play any games in the background.
I'm not happy with any marketplace. For top quality liquid names all could work, but for average quality ones each suck in one or more thing. A major site (probably their agent) lowballed me at Sedo, and I accepted a very low offer, because I didn't know who the buyer was. Now I feel scammed. Flipper got 10K maybe, I got 100. I feel we can almost never connect with actual buyers.
