Well, the only thing OVT will do is assist you with determining if the domain gets any kind of traffic. The truth is - if you own it, only you would know. Here is the problem I see...
What would you use this domain name for besides an adult site?
Considering its a .us domain name - its also less likely to be desired by the adult industry, they prefer developing sites on the .com - (There tough to sell unless com).
So, is the domain getting any kind of traffic?
