Shuts down a room. Moves all local users and room aliases automatically
|

to a new room if `new_room_user_id` is set. Otherwise local users only
|
|
|
|
leave the room without any information.
|
|
|
|
|
|
|
|
The new room will be created with the user specified by the
|
|
|
|
`new_room_user_id` parameter as room administrator and will contain a
|
|
|
|
message explaining what happened. Users invited to the new room will
|
|
|
|
have power level `-10` by default, and thus be unable to speak.
|
|
|
|
|
|
|
|
The local server will only have the power to move local user and room
|
|
|
|
aliases to the new room. Users on other servers will be unaffected.

Args:
|

|
room_id: The ID of the room to shut down.

User who requested the action and put the room on the
|
|
|
|
blocking list.
|
|
|
|
new_room_user_id:
|
|
|
|
If set, a new room will be created with this user ID
|
|
|
|
as the creator and admin, and all users in the old room will be
|
|
|
|
moved into that room. If not set, no new room will be created
|
|
|
|
and the users will just be removed from the old room.
|
|
|
|
new_room_name:
|
|
|
|
A string representing the name of the room that new users will
|
|
|
|
be invited to. Defaults to `Content Violation Notification`
|
|
|
|
message:
|
|
|
|
A string containing the first message that will be sent as
|
|
|
|
`new_room_user_id` in the new room. Ideally this will clearly
|
|
|
|
convey why the original room was shut down.
|
|
|
|
Defaults to `Sharing illegal content on this server is not
|
|
|
|
permitted and rooms in violation will be blocked.`
|
|
|
|
block:
|
|
|
|
If set to `true`, this room will be added to a blocking list,

preventing future attempts to join the room. Defaults to `false`.

|
kicked_users: An array of users (`user_id`) that were kicked.

|

failed_to_kick_users:
|
|
|
|
An array of users (`user_id`) that that were not kicked.
|
|
|
|
local_aliases:
|
|
|
|
An array of strings representing the local aliases that were
|
|
|
|
migrated from the old room to the new.
|
|
|
|
new_room_id: A string representing the room ID of the new room.
