There are, at the moment, two listings on Ebay with the same title 1981 alembic series one bass guitar.
This one appears to be fraudulent. Apparently, the more people who report a fraudulent listing, the sooner it gets taken down, and less likely someone will get ripped off. So if you agree that it's probably a fraud, then you can report by clicking on the report item link on the right side under seller's address.
The account has probably been hijacked, so the listed seller in this case is a victim as well.
