In addition to the standard RFC 1459 channel modes, BlabberNet supports a number of extra useful channel modes. Behavioural modes affect the general behaviour of channels. Channel access modes restrict access to the channel. Message filtering modes block or alter messages to the channel. Flood protection modes help mitigate abuse from flood bots or users.
| Mode | Description |
|---|---|
| +u | Puts the channel into Auditorium Mode. |
| +A | Allows any channel user (including non-ops) to invite others to the channel. |
| +D | New users are not shown in the channel until they speak. |
| +L <channel> | If channel reaches user limit set by +l mode, redirect new users to channel. |
| +N | Prevents users on the channel from changing their nicks. |
| +Q | Prevents anyone except Services from kicking users off the channel. |
| Mode | Description |
|---|---|
| +e <mask> | Creates a ban exception where mask is in nick!user@hostname format. Users matching this are not subject to banning. |
| +I <mask> | Creates an invite exception where mask is in nick!user@hostname format. Users matching this can join an invite-only channel without an invite. |
| +z | Blocks non-SSL clients from joining the channel. |
| +J <seconds> | Prevents rejoin after kick for the specified number of seconds. |
| +R | Prevents unregistered users from joining the channel. |
| Mode | Description |
|---|---|
| +c | Blocks messages which contain colour codes. |
| +d <seconds> | Blocks messages from new users until they have been in the channel for seconds. |
| +B | Blocks messages with too many uppercase letters. See CAPS Block for more information. |
| +C | Blocks CTCP messages directed to the channel. |
| +G | Censors messages to the channel based on the network's censor configuration. See Censoring for more information. |
| +M | Blocks messages from unregistered users. |
| +S | Removes colour formatting from IRC messages. |
| +T | Blocks /NOTICEs to the channel from users without half-op status or higher |
| +g mask | Blocks messages matching the given mask. See Censoring for more information. |
| Mode | Description |
|---|---|
| +f [*]<lines>:<seconds> | Message flood protection, kicks users who exceed lines of chat in seconds of time. With * the user is banned too. |
| +j <joins>:<seconds> | Join flood protection, limits new user joins to joins in seconds. |
| +F <changes>:<seconds> | Nick flood protection, prevents nick changes which exceed changes in seconds. |
