> To my view, there's a world of difference between "You can't use PayPal as a payment processor for gun sales" and "You can't use PayPal to pay pals back for covering your range fees last Saturday."

Firearms are for absolutely no reason what-so-ever taboo on most payment processors. The AUP is broad enough to cover both because the pearl clutchers don't see a difference. The best part of this is "certain firearm parts or accessories" as if they had a qualified expert anywhere in their company that could identify a bolt from a slide. It's deliberately written to trap you, and now, extort you for $2,500.
