There is a thriving market in amateur adult modeling and porn.
I am thinking of writing an e-book about it.
I would preorder such an ebook.
Not OP, but my insight: Adult entertainers use Snapchat as a distribution channel for their own self-made videos. Some offer their Snapchat stories for free and try to up-sell you, others charge you for giving you access to their stories. Payment is through Patreon or PayPal or some other common payment platforms.
