What are some of the best Adult Social Networks to join for Conversion?

I'm starting a new Halloween campaign for a website I market for.

Unfortunately I'm not sure which sites are the best to market on and get the most exposure to the right clientele .

This is my first time marketing for the adult industry and my research just keeps turning up dead ends.

Any help would be greatly appreciated.

 

reddit has few adult communities too.

 

You could check out some facebook groups.
