I'm working on social media info but so far nothing. What I have been able to find so far.
Picture was taken by @istolethetv in 2008 at a leather fetish event in NYC. He says she was a vendor, the sign in front of her tracks to an Etsy shop Phetishnation. Run by a Ms Thorny, who may also go by Mistress Thorny.
Edit to add, found her in Insta, no good pictures though. @mistress_thorny, she also is tied in with the @ravenous_group
