I don't want her name and address. I just want her stuff.
Just so I'm sure I have this right. A guy who fantasizes about being/having sex with anthropomorphic animals is seeking to track down a 17 year old girl to buy her collection of anthropomorphic ponies.
I'm not sure if she's going to want them back from you after you're done with them, dude.
Good point. Somewhat wrong assumption. Don't care. Want her stuff. At the least it'll be safe and available if she does want it back.
If it helps you, think of it as me preserve the memory of destroyed childhood.
