jeff sIt depends on the context in which you saw this, Cy. There are plenty of members out there who assembled a good feedback rating, then became non-registered because either a) they chose to, or b) they were kicked off (NARUed). However, once someone is kicked off, they do not disappear from the eBay database - you can still look up their feedback, and their feedback is visible in the fb profiles of others (with the designation that they are NotARegisteredUser).
I'm 99.9% sure that if you are NARU, you cannot under any circumstances sell. If you have auctions running, and in the middle of those auctions, you are kicked off, all of your current auctions will be immediately halted and will disappear from the database.
