I temporarily fixed the problem by extracting that code from the plugin.

Find in includes/cron/cleanup.php

($hook = vBulletinHook::fetch_hook('cron_script_cleanup')) ? eval($hook) : false;

Add before

while ($thread = $vbulletin->db->fetch_array($threads))
{
    $thread['open'] = 10;
    $threadman =& datamanager_init('Thread', $vbulletin, ERRTYPE_SILENT, 'threadpost');
    $threadman->set_existing($thread);
    $threadman->delete(false, true, NULL, false);
    unset($threadman);
}

Now "Top Thread Starters" will get updated every hour.

I am glad that it helps.

But I didn't understand your point. The code you suggest to add in cleanup.php is already there.
