 IRC (Internet Relay Chat) and ICB (Internet Citizen's Band) are two separate

 ICB is an older and simpler protocol, basically a subset of IRC.

 .Sh BUGS
 On ICB, a moderator (channel operator) can leave the group (channel) and
 rejoin later, preserving his status, as compared to IRC, where the channel
 would be left operator-less in this case.
 The proxy does not currently detect the operator status on rejoin in this
 case, and the IRC client will (temporarily) show the channel op-less.
