@f0x Okay, so mentioning LiberaChat will cause an immediate revocation of the official channel status. Now, what about writing a bot to send everyone a message when they're joining the channel. That should be fine according to their rules.
@niconiconi yeah, or kicking all users with a message
and not just big channels, our hackerspace moved quickly and has now suddenly lost ChanServ registration, with old policy giving at least 90 days and only reclaiming channels when asked afaict
