Yeah, EBay’s gonna pull that for a WIDE number of reasons…
For one, they don’t allow selling of souls, spirits, or any other ‘body parts’.
For two, there’s absolutely no way the buyer could confirm that they have received what was promised, nor the seller confirm delivery of anything but a jar. Certificate of authenticity? Authenticated by *who*?
For three… Fictional characters are not known to leave behind ghosts. There’s a few that should have died long, long ago, but that’s closer to being a zombie or lich, not a ghost.
I give it a D-Minus.
