I dont think they do, but then everybody thinks their domains are Super premium
I consider these names to be my very best and i will never let them drop. They are all 3+ years old and all .com
So i'm not ashamed of them if thats what you mean. Sedo would be the obvious choice since they have a strong reputation. If you wanted to start an auction aimed at end users competing for your best adult domains would you go for Sedo all the way? eBay or something else? If so what?
