Someone who left me feedback is "not a registered user." What does this mean?
A registered user's status may change if they ask to cancel their membership or if they're suspended from trading on eBay. If this occurs, there will be no changes to your feedback rating or to the comments left by that user when they were registered.
A nonregistered account does not differentiate which of the two it is suspension or cancellation.
As far as coming back with the same account, I am not sure.
