+Relays MAY delete or stop publishing any referenced events that have an identical `pubkey` as the deletion request.  Clients may hide or otherwise indicate a deletion status for referenced events.
 
 ## Client Usage
 
-Clients MAY choose to fully hide any events that are referenced by valid deletion events.  This includes text notes, direct messages, or other yet-to-be defined event kinds.  Alternatively, they MAY show the event along with an icon or other indication that the author has "disowned" the event.  The `content` field may also be used to replace the deleted events own content, although a user interface should clearly indicate that this is a deletion reason, not the original content.

 A client MUST validate that each event `pubkey` referenced in the `e` tag of the deletion request is identical to the deletion request `pubkey`, before hiding or deleting any event.  Relays can not, in general, perform this validation and should not be treated as authoritative.
 
+Clients display the deletion event itself in any way they choose, e.g., not at all, or with a prominent notice.

 ## Relay Usage
 
 Relays MAY validate that a deletion event only references events that have the same `pubkey` as the deletion itself, however this is not required since relays may not have knowledge of all referenced events.
