I'm not the commenter, but about 20 years ago when ebay owned paypal still, I sold 26 iPod nanos in a big sale on ebay. Everyone received theirs except one guy, and the tracking showed the shipper lost it, in that the package just stopped being scanned in the USPS system halfway through. He complained, completely understandable! eBay froze my account, froze the payments for all 26, and I never saw the money ever again.

They wouldn't let me just refund the one customer. I had to prove the other 25 were delivered, so I did that. Then I had to prove they actually got iPods, so I linked them to the reviewed transactions that showed people were happy with the iPods. So then I had to prove my identity to eBay. They wanted my license, so I did that. Then a utility so I sent my light bill. Then my phone bill. Then my natural gas bill. Then my lease. Then they asked for my passport, which I did not have at that time. Suddenly nothing could be done without the passport, and they'd keep the money for 180 days and then mail me a check. Except then they said they were keeping the money anyway because I didn't provide a passport. Five grand, gone.

From that day on I'd have multiple eBay accounts at all times, spread things out around them so that when (not if, when) they would freeze an account for a review, I'd just cancel everything, refund whatever purchase was in review, and never use that account again. I learned that the review process is just a delay process to make you think there was progress when you'd already been banned but since you thought there was a chance, you'd keep busy in the no-go queue for however long you interacted with the bot before you gave up rather than calling support.
