I asked them one month ago about adult domains. They answered that they do not have excpicit content for parked domain pages, but only dating and souch type.
I like the idea of parking there mainstream domains. Currently i have 2 domains parked , and forgoten, at
http://www.nowiw.com/
They give the same advantages. In one year my domains make an average 1k daily each one. Now i try to place some ads but the system is f... stupid. I 'll see.
