For example, an admin or owner is automatically a moderator, so if an occupant is granted an affiliation of admin then the occupant will by that fact be granted a role of moderator; similarly, when an occupant is granted an affiliation of member in a moderated room, the occupant automatically has a role of participant. However, the loss of the admin affiliation does not necessarily mean that the occupant no longer has a role of moderator (since a "mere" occupant can be a moderator). Therefore, the role that is gained when an occupant is granted a certain affiliation is stable, whereas the role that is lost when an occupant loses a certain affilitation is not hardcoded and is left up to the implementation. Since a client cannot predict what the role will be after revoking a certain affiliation, if it wants to remove both the admin/owner affiliation and the moderator role at the same time then it must specifically request the role change in addition to the affiliation change by including both the 'role' attribute and the 'affiliation' attribute.</p>

However, if there is no activity in the room then the room MAY periodically poll its occupants to ensure that there are no "ghost users" in the room (e.g., by using presence probes or &xep0199;). If the user's server goes offline or connectivity is lost between the user's server and the MUC service to which the user is connected (e.g., in federated communications), the MUC service is responsible for monitoring error stanzas it receives in order to determine if the user has gone offline. If the MUC service determines that the user has gone offline, it must treat the user as if the user had itself sent unavailable presence.</p>

<p>Deployment experience has shown that sometimes a user can appear to be an occupant in a room even though the user's real JID has gone offline since joining. Such users are called "ghosts". To help prevent ghost users, a MUC service SHOULD remove a user if the service receives a delivery-related error in relation to a stanza it has previously sent to the user (in this context, the delivery-related errors are &gone;, ¬found;, &recipient;, &redirect;, &remoteserver;, and &timeout;). A MUC service MAY also use &xep0199; to periodically check the availability of room occupants.</p>
