If you recall, when this started, seller had a pretty good feedback but has not done anything on eBay in a long time.
So originally this was a legitimate account.
At some point, I am guessing, s/he lost access and malicious users took over.
One probably would not have sent money to 0 feedback account.
Paypal was either done in same way or a throw away account.
After you sent noney, they delay by generating tracking number with actual package which you can check progress on.
As soon as money are in paypal they are withdrawn and cashed out.
You get your money back from paypal. Thieves get your money. The only looser is eBay/paypal/insurance.
