I have two sites I built a few years ago. NSFWSelfies.com and Teenlr.com . Both were registered a few years ago. They basically have no traffic. I always wanted to develop them, but I never had the time to do it. I saw them as valuable domains and that's why I kept them over the years.
Both are wordpress sites, and NSFWSelfies is pretty decent. It also has social media and a facebook account with over 400 organic followers, and although I don't mind handing them over, I'm selling them as domains, not developed sites with traffic.
Reply here with a contact method if you're interested. I don't mind if you tell me they're worthless and I should let them expire either
Cheers!
