I've been to TA a couple of times and they do seem to cut anything that might shade the light from any destination. It has a policy of if it doesn't promote or sound good to everyone then it doesn't make the forum.
But to know Sosua you don't need to be on any site devoted travel site, just google it and you will know.
I say that but funnily enough my first trip to Sosua was completely innocent, I looked for a bargain to the Caribbean and got sent to the Playa Dorada complex. 24 hours there and was needing to get out, took a cab to Sosua and I thought the girls were easy, simply a different culture and so obviously was quite into it, until it clicked and all of a sudden I didn't feel quite so special, lol. So there are innocent bargain hunters that will take 2 weeks in Sosua at CM unaware of what or where they are going, but I don't believe anyone who knows of this site possibly could be so unaware. She's probably a he on 'I miss sexy chics trip', 'oh, I'll be pink'.
