I think that hubs and good interlinking may be very good for the domain & free sites on it. Actually, everything what makes surfer to be active and stay is perfect

thai girls hub.
I was inspired by Greenie's bottom banners, so I've added similar ads to all the freesites on above mentioned domain and fetish free sites on
www.fetishroot.com
