## 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.

## Deleting a Deletion
Publishing a deletion event against a deletion has no effect. Clients and relays are not obliged to support "undelete" functionality.

## Deleting Replaceable Events
Because of their changing nature it's hard to get rid of all instance of a replaceable event (ranges `10000...19999` and `30000...39999`). We also don't want to publish a `kind:5` targeting an `a` reference and thus permanently delete any future events that could possibly have the same specifieds `kind` and `d`-tag forever.
So instead to delete a replaceable event we **overwrite** it with an event with the same `kind` and `d`-tag, plus a tag `["deleted"]` specifying no other tags.
