 Events sent by users to groups (chat messages, text notes, moderation events etc) MUST have an `h` tag with the value set to the group _id_.
 
-`h` tags MAY include the group's name as the second argument. This allows `unmanaged` groups to be assigned human-readable names without relay support.

 ## Timeline references
 
 In order to not be used out of context, events sent to these groups may contain references to previous events seen from the same relay in the `previous` tag. The choice of which previous events to pick belongs to the clients. The references are to be made using the first 8 characters (4 bytes) of any event in the last 50 events seen by the user in the relay, excluding events by themselves. There can be any number of references (including zero), but it's recommended that clients include at least 3 and that relays enforce this.

 ### Using `unmanaged` relays
 
 To prevent event leakage, when using `unmanaged` relays, clients should include the [NIP-70](70.md) `-` tag, as just the `previous` tag won't be checked by other `unmanaged` relays.
+
+Groups MAY be named without relay support by adding a `name` to the corresponding tag in a user's `kind 10009` group list.

 Even though it's ultimately impossible to restrict the spread of information on the internet (for example, one of the members of the closed group may want to take an event intended to be restricted and republish it to other relays), most relays would be happy to not facilitate the acts of these so-called "pirates", in respect to the original decision of the author and therefore gladly reject these republish acts if given the means to.
 
 This NIP gives these authors and relays the means to clearly signal when a given event is not intended to be republished by third parties.

+## Clearing Protected Events
+
+The `kind:20070` ephemeral event asks the tagged relay to delete all of the author's protected events.
+
+Relays MUST require authentication to fulfill the clearing request. Too old `kind:20070` events MUST be ignored.
+
+The event is useful to prevent replaceable and addressable events from becoming outdated after an user edits their [NIP-65](65.md) write relays.

+```jsonc
