By any chance was your dormant account hijacked?
I ran across his video a few days ago, it describes in detail a scam worked through a hijacked account.

Trying to look into that with eBay now.
When (and if) I get a response I will post it.
I have not interacted with that account in years, so if there was recent activity that would explain something.
