you know, actually you are correct viper, forbidden channels won't be in the channel list unless by some odd chance someone was doing a /list at the same time someone was in the channel, but that would either be caused by opers dwelling in forbidden channels or split second timing or a 3rd party module has bots or something else going on. In the case of the later, nothing we can do about that. It's up to module coders to handle such things within their own modules.
