PayPal case opened against me by buyer

[swarmee]

Get your documents in order:
1) Where the item was sold from (eBay, board message, emails, etc).
2) Find your tracking number to prove delivery.

There is a scam going around because eBay auctions only stay in eBay's history for two months. So sellers enter the tracking number there, to prove the item was delivered, and normally throw out the tracking receipt once the item shows delivered. So if they get a PayPal chargeback between 3-6 months, 90% of sellers won't have the tracking number to prove it was delivered.
My expectation is that PayPal will either force you to take the return, or they'll refund the buyer out of their own pocket and possibly lock the buyer's account.
