<p>If the <code>my_stories_from</code> is set, peers will be added/removed only to/from the story blocklist; otherwise, they will be added/removed to/from the the main blocklist. </p>

Peers in the main blocklist won't be able to write messages to you, view your status, photo and stories. </p>

<p>Use <a href="/method/contacts.getBlocked">contacts.getBlocked</a> to fetch the list of blocked peers; as usual, the <code>my_stories_from</code> flag can be used to fetch the story blocklist or the main blocklist, and the <code>offset</code>/<code>limit</code> parameters are used for <a href="/api/offsets">pagination »</a>. </p>
<p><a href="/method/contacts.setBlocked">contacts.setBlocked</a> may also be used to completely replace the contents of an entire blocklist in bulk: just pass the blocklist type in <code>my_stories_from</code>, the full list of IDs to block in <code>id</code> and the length of the list passed to <code>id</code> in <code>limit</code>: the server will completely replace the specified blocklist.</p></div>

<p>This flag is used to specify the expiration TTL of the passed geolocation (i.e. the geolocation will expire after <code>self_expires</code> seconds); pass `0x7fffffff`` to disable expiry, 0 to make the current geolocation private. </p>
<p>The method will also return a list of nearby users and chats, but only if the passed expiration TTL is not equal to zero.<br>
Users may still fetch nearby users and chats without making their geolocation public by simply not setting the flag, see <a href="#fetching-nearby-users--geogroups">here »</a> for more info. </p>
<p>While the geolocation of the current user is public, clients should update it in the background every half-an-hour or so (or in any case before the expiration date specified with <code>self_expires</code>), while setting this flag. </p>
<p>If the new location is more than 1 KM away from the previous one, or if the previous location is unknown, the <code>background</code> flag should be set when invoking <a href="/method/contacts.getLocated">contacts.getLocated</a>.</p></div>
