First off - This has nothing to do with Dynadot ... it happens in most live auctions.
But I just saw several Adult Domains go for 18-20 Months of Revenue that probably won't have any traffic by the end of January (If not already). Yes the traffic stats were nice looking. But Adult traffic is the lowest paying out there ... "Why buy the cow when the milk is free?" comes to mind. Far too much Free Porn out there and many of the Dating affiliate programs are even tired of that particular type of traffic.
None of my business really - but when the domains : 1) Aren't even keyword rich (They had numbers representing letters for Pete's sake). 2) Have NO backlinks or PR. 3) Are all expiring on the same day at the same registrar (Easy to assume same previous owner).
You might want to take a breath and think it over ... Just Sayin'
