Help with ignoring users

[CoffeeLovesYou]

Hi.
So I made it so you can ignore everyone including mods/admins.
This is because ONE usergroup is able to moderate a certain forum. However, they aren't staff, and still should be able to be ignored.
How can I edit the profile.php ignore part, particularly this line:

PHP Code:

if (!$vbulletin->options['ignoremods'] AND can_moderate(0, '', $userinfo['userid'], $uglist) AND !($permissions['adminpermissions'] & $vbulletin->bf_ugp_adminpermissions['cancontrolpanel']))
            {
                standard_error(fetch_error('listignoreuser', $userinfo['username']));
            } 


to make it so if the person they are trying to ignore is a member of usergroups a, b, c, d, e, etc.. they can't be ignored?

Thanks!
