Okay so I recently got some more info on the guy who was stealing my adoptables and selling them elsewhere.

Normally I would never, ever, in a million years share the name of someone's PayPal but in this case I would prefer that people did not get scammed.

If anybody is buying something from an account under the name of "Samuel Byerley " it is likely a scam, so do your research beforehand or just avoid altogether.

Thank you to all who have informed and helped me with this, I am sorry it happened, and hopefully there won't be too many further issues.
