Okay, so take this tidbit with several grains of salt, maybe a little lime too. I'm not sure if it's entirely above the law or even advisable to do this, and I wouldn't even recommend this if you had more options. But here's something that's worked for me. Especially in my case, where the scammer still lived at home. I was pretty desperate, but this worked for me. I have no idea the value of your snakes, as I don't do BPs, but I was nearly scammed out of $5,000.
Get a bunch of post cards. Also, get a couple oversized manilla envelopes, like the 11x14 or whatever. The big ones.
Now write on the postcards in a thick sharpie things like "HOW DARE YOU STEAL FROM ME?" and "I CANNOT BELIEVE YOU COMMITED MAIL FRAUD!" things like that. Also, write it on the outside of the big envelope, in thick dark print so that everybody--the mailman, his parents, everybody! can read it when (and even before) it reaches it's intended destination. Whoever picks up the mail, will see that's there's something going on. Huge shame factor. I mean, the writing on the outside of the envelope clearly needs explaining somewhere!! In the bigger envelopes, print off your proof and perhaps this thread and include it in the envelopes that get mailed to the parents or the other parties.
Make sure you mail it to the address you shipped to. Also, it never hurts to "accidentally" mail a couple of those bad boys to his family members, girlfriend, church, etc. In my case, one of those post cards getting mailed to Grandma and the church pastor got me my end of a swap. The kid cannot delete it, or hide it from his parents, and it forces him to face the issue. Especially since Grandma read that my scammer was actively committing mail fraud, and could be fined/jailed/etc.
I wish you luck. And once more, I have no idea if this constitutes harassment, or what, but I was out of options and this got me my end of a swap. Use your judgement.
