+</li>
+<li>
+<p><code>name</code> - Is optional and filters to only return users with user ID localparts
+<strong>or</strong> displaynames that contain this value.</p>
+</li>
+<li>
+<p><code>guests</code> - string representing a bool - Is optional and if <code>false</code> will <strong>exclude</strong> guest users.
+Defaults to <code>true</code> to include guest users. This parameter is not supported when MSC3861 is enabled. <a href="https://github.com/matrix-org/synapse/pull/15582">See #15582</a></p>
+</li>
+<li>
+<p><code>admins</code> - Optional flag to filter admins. If <code>true</code>, only admins are queried. If <code>false</code>, admins are excluded from
+the query. When the flag is absent (the default), <strong>both</strong> admins and non-admins are included in the search results.</p>
+</li>
+<li>
+<p><code>deactivated</code> - string representing a bool - Is optional and if <code>true</code> will <strong>include</strong> deactivated users.
+Defaults to <code>false</code> to exclude deactivated users.</p>
+</li>
+<li>
+<p><code>limit</code> - string representing a positive integer - Is optional but is used for pagination,
+denoting the maximum number of items to return in this call. Defaults to <code>100</code>.</p>
+</li>
+<li>
+<p><code>from</code> - string representing a positive integer - Is optional but used for pagination,
+denoting the offset in the returned results. This should be treated as an opaque value and
+not explicitly set to anything other than the return value of <code>next_token</code> from a previous call.
+Defaults to <code>0</code>.</p>
+</li>
+<li>
+<p><code>order_by</code> - The method by which to sort the returned list of users.
+If the ordered field has duplicates, the second order is always by ascending <code>name</code>,
+which guarantees a stable ordering. Valid values are:</p>
+<ul>
+<li><code>name</code> - Users are ordered alphabetically by <code>name</code>. This is the default.</li>
+<li><code>is_guest</code> - Users are ordered by <code>is_guest</code> status.</li>
+<li><code>admin</code> - Users are ordered by <code>admin</code> status.</li>
+<li><code>user_type</code> - Users are ordered alphabetically by <code>user_type</code>.</li>
+<li><code>deactivated</code> - Users are ordered by <code>deactivated</code> status.</li>
+<li><code>shadow_banned</code> - Users are ordered by <code>shadow_banned</code> status.</li>
+<li><code>displayname</code> - Users are ordered alphabetically by <code>displayname</code>.</li>
+<li><code>avatar_url</code> - Users are ordered alphabetically by avatar URL.</li>
+<li><code>creation_ts</code> - Users are ordered by when the users was created in ms.</li>
+<li><code>last_seen_ts</code> - Users are ordered by when the user was lastly seen in ms.</li>
+</ul>
+</li>
+<li>
+<p><code>dir</code> - Direction of media order. Either <code>f</code> for forwards or <code>b</code> for backwards.
+Setting this value to <code>b</code> will reverse the above sort order. Defaults to <code>f</code>.</p>
+</li>
+<li>
+<p><code>not_user_type</code> - Exclude certain user types, such as bot users, from the request.
+Can be provided multiple times. Possible values are <code>bot</code>, <code>support</code> or &quot;empty string&quot;.
+&quot;empty string&quot; here means to exclude users without a type.</p>
+</li>
+<li>
+<p><code>locked</code> - string representing a bool - Is optional and if <code>true</code> will <strong>include</strong> locked users.
+Defaults to <code>false</code> to exclude locked users. Note: Introduced in v1.93.</p>
+</li>
+</ul>
+<p>Caution. The database only has indexes on the columns <code>name</code> and <code>creation_ts</code>.
+This means that if a different sort order is used (<code>is_guest</code>, <code>admin</code>,
+<code>user_type</code>, <code>deactivated</code>, <code>shadow_banned</code>, <code>avatar_url</code> or <code>displayname</code>),
+this can cause a large load on the database, especially for large environments.</p>
+<p><strong>Response</strong></p>
+<p>The following fields are returned in the JSON response body:</p>

+</li>
+<li>
+<p><code>from</code>: string representing a positive integer - Is optional but used for pagination,
+denoting the offset in the returned results. This should be treated as an opaque value and
+not explicitly set to anything other than the return value of <code>next_token</code> from a previous call.
+Defaults to <code>0</code>.</p>
+</li>
+<li>
+<p><code>order_by</code> - The method by which to sort the returned list of media.
+If the ordered field has duplicates, the second order is always by ascending <code>media_id</code>,
+which guarantees a stable ordering. Valid values are:</p>
+<ul>
+<li><code>media_id</code> - Media are ordered alphabetically by <code>media_id</code>.</li>
+<li><code>upload_name</code> - Media are ordered alphabetically by name the media was uploaded with.</li>
+<li><code>created_ts</code> - Media are ordered by when the content was uploaded in ms.
+Smallest to largest. This is the default.</li>
+<li><code>last_access_ts</code> - Media are ordered by when the content was last accessed in ms.
+Smallest to largest.</li>
+<li><code>media_length</code> - Media are ordered by length of the media in bytes.
+Smallest to largest.</li>
+<li><code>media_type</code> - Media are ordered alphabetically by MIME-type.</li>
+<li><code>quarantined_by</code> - Media are ordered alphabetically by the user ID that
+initiated the quarantine request for this media.</li>
+<li><code>safe_from_quarantine</code> - Media are ordered by the status if this media is safe
+from quarantining.</li>
+</ul>
+</li>
+<li>
+<p><code>dir</code> - Direction of media order. Either <code>f</code> for forwards or <code>b</code> for backwards.
+Setting this value to <code>b</code> will reverse the above sort order. Defaults to <code>f</code>.</p>
+</li>
+</ul>
+<p>If neither <code>order_by</code> nor <code>dir</code> is set, the default order is newest media on top
+(corresponds to <code>order_by</code> = <code>created_ts</code> and <code>dir</code> = <code>b</code>).</p>
+<p>Caution. The database only has indexes on the columns <code>media_id</code>,
+<code>user_id</code> and <code>created_ts</code>. This means that if a different sort order is used
+(<code>upload_name</code>, <code>last_access_ts</code>, <code>media_length</code>, <code>media_type</code>,
+<code>quarantined_by</code> or <code>safe_from_quarantine</code>), this can cause a large load on the
+database, especially for large environments.</p>
+<p><strong>Response</strong></p>
+<p>The following fields are returned in the JSON response body:</p>

+<p>By default, the API deletes media ordered by descending creation date and ascending media ID.
+The newest media is deleted first. You can change the order with parameters
+<code>order_by</code> and <code>dir</code>. If no <code>limit</code> is set the API deletes <code>100</code> files per request.</p>
+<p>The API is:</p>

+<p>Shadow-banning is a useful tool for moderating malicious or egregiously abusive users.
+A shadow-banned users receives successful responses to their client-server API requests,
+but the events are not propagated into rooms. This can be an effective tool as it
+(hopefully) takes longer for the user to realise they are being moderated before
+pivoting to another account.</p>
+<p>Shadow-banning a user should be used as a tool of last resort and may lead to confusing
+or broken behaviour for the client. A shadow-banned user will not receive any
+notification and it is generally more appropriate to ban or kick abusive users.
+A shadow-banned user will be unable to contact anyone on the server.</p>
+<p>To shadow-ban a user the API is:</p>
+<pre><code>POST /_synapse/admin/v1/users/&lt;user_id&gt;/shadow_ban
+</code></pre>
+<p>To un-shadow-ban a user the API is:</p>
+<pre><code>DELETE /_synapse/admin/v1/users/&lt;user_id&gt;/shadow_ban
+</code></pre>
+<p>An empty JSON dict is returned in both cases.</p>
