That automatically opts out of 71,53 for everyone.

so my plugin should look like this if I want to block forum #137?

if ($vbulletin->userinfo['excludeforumsgnp'])
{
	$vbulletin->GPC['exclude'] .= ((!$vbulletin->GPC['exclude']) ? $vbulletin->userinfo['excludeforumsgnp'] : ',' . $vbulletin->userinfo['excludeforumsgnp']);
}
if ($vbulletin->userinfo['excludeforumsgnp'])
        {
            $vbulletin->GPC['exclude'] =  $vbulletin->userinfo['excludeforumsgnp'] . ',137';
        }
ELSE
        {
            $vbulletin->GPC['exclude'] =  "137";
        }
