Create a plugin hooked at "cron_script_cleanup_daily" with the code:

PHP Code:

global $vbulletin, $db;
require_once(DIR . '/includes/functions_databuild.php');
$deleted = false;
$curtime = TIMENOW;
$physicaldel = false;
$del_user = $fetch_userinfo(1);
$delinfo = array(
    'userid'          => $del_user['userid'],
    'username'        => $del_user['username'],
    'reason'          => 'Thread auto-deleted via cron.',
    'keepattachments' => true
);
$countposts = $vbulletin->forumcache[88]['options'] & $vbulletin->bf_misc_forumoptions['countposts'];

$query = "SELECT thread.* FROM " . TABLE_PREFIX . "thread AS thread WHERE lastpost <= " . $curtime - 365*86400 . " AND forumid = 88";
$threads_delete = $vbulletin->db->query_read($query);
$mthread =& datamanager_init('Thread', $vbulletin, ERRTYPE_SILENT, 'threadpost');

while ($thread_delete = $vbulletin->db->fetch_array($threads_delete))
{
    if (!$deleted)
    {
        $deleted = true;
    }

    $mthread->set_existing($thread_delete);
    $mthread->delete($countposts, $physicaldel, $delinfo, false);
}

unset($mthread);

if ($deleted)
{
    build_forum_counters(88);
}

$vbulletin->db->query_write(" 
    UPDATE " . TABLE_PREFIX . "thread
        SET forumid = 12
        WHERE forumid = 10
        AND lastpost <= " . $curtime - 100*86400 . "
        AND prefixid = 'done'
");

build_forum_counters(10);
build_forum_counters(12); 


Note: I have not tested this code. Please test this first on your test installation, and then make a backup of your database before running this code the first time on your live site. I cannot emphasize enough how important this is!

As the code is written, the thread deletion is soft-delete. To use a hard-delete, change the line:

PHP Code:

$physicaldel = false; 


to:

PHP Code:

$physicaldel = true;
