A user's status may be indicated as Not a Registered User for several reasons:

• If a user requests to be unregistered from eBay.
• If a user is suspended from using eBay. While suspensions are rare, eBay reserves the right to suspend users at our discretion. In most cases, we do so as a result of an eBay site rule violation or violation of the User Agreement. If you have any question about eBay's terms and conditions, see our User Agreement or review policies of our SafeHarbour Team.
• If you see the words, "Not a Registered User" next to an eBay member's User ID, this means that this person unregistered from eBay after the listing closed. Because only registered eBay members can participate on eBay, you are not obligated to buy or sell from this person.

When a user's status is changed to Not a Registered User, all feedback left by this user remains unaltered. Prior to 1999, however, as noted in some profiles, feedback was converted to neutral when a user became no longer registered.
