A lot of kids talk in this post. Grow-up guys, this is pure business. Obviously this site does not make money anymore. It was just crushed by competitors.
Even if it is unique in his style, people today are not too much after forums but more for see and go (eg. xhamster, pornhub ... with good BDSM sections) .
Also real life BDSM sessions & workshops increased lately through sites like fetlife that support a lot this kind of events.
In all those cases the payment is done via commercials and not by people begging whatever site owner to return

If someone would like to take-over this site and turn it commercial than will survive otherwise will just disappear
