Of course you'll get banned for posting these type of things. It's only a matter of someone reporting you if pinterest doesn't catch you the first time around.
Anyways, why would you promote adult? The majority of their userbase are womenyour conversions would be pretty low unless you offer them a dating offer that caters to women.
I've seen some guys do this but it's not really profitable. Since most of the users are women or ... guys trying to make money) Also. If these moms start seeing your pins be sure you will get reported since pinterest doesnt have an adult filter and I think I even read in their TOS that nudity is against the rules. So maybe bikinis but again .. angry moms.
