Collection agencies are known to do this, yes, if you don’t respond to their emails/letters/phone calls.

It was fifteen years ago now, so many of the specifics are fuzzy at this point.
As I recall though, I was still in contact with PayPal support at the time; but it had been a long and drawn-out process due to how slow they were to investigate/respond, and the threatening visit was the first I had heard from a collection agency at all. It was not that I had been ignoring emails/letters/phone calls from them, or ignoring PayPal support.
It felt more like PayPal had contacted them as a means to get their money back, while stringing me along.
As I said: it was not exactly the same situation as this, since I was the seller.
I would hope that their procedures are better now after fifteen years; but if a chargeback is successful, and PayPal end up saying that you owe them money, you cannot ignore it and decide that your account with them is forfeit - even if that seems unfair. They will come after you for it.
I did look up some of my old emails relating to it: emails to the buyer - who did not delete their account immediately, but tried to make excuses first; PayPal support; and discussing it with friends.
And honestly, I was too young and naive to know how to handle it properly by myself - so much of this thread feels very familiar and is bringing back bad memories.
I'm inclined to believe that
TheGreatJordan is not trolling, and the "inconsistencies" or unexpected responses that people are pointing at is a result of being young and freaking out at being scammed out of what would be a significant amount of money at that age (and to many, significant at any age).
I can look back now and see how there are many things I should have handled differently, but I didn't know any better at the time.
