I haven't haven't had a chance to test this, but I think if you use hook location newpost_process you can use code like this:

PHP Code:

if ($type == 'thread' AND $post['visible'] AND !can_moderate($foruminfo['forumid']))
{
    if (strpos($post['message'], 'viagra') !== false)
    {
        $dataman->set('visible', 0);
        $post['visible'] = 0;
    }
}
