Extended bans
Extbans extend +b (and the +e / +I exceptions) beyond a plain nick!user@host mask. Use them
as MODE <#channel> +b <letter>:<value>. The server advertises EXTBAN=,aGAbcgjmnrsy and
ACCOUNTEXTBAN=a.
There are two kinds. Matching extbans decide whether a user matches (for a ban or an exception); acting extbans restrict a specific action instead of blocking the join.
Matching extbans#
| Letter | Name | Matches |
|---|---|---|
a | account | A services account glob, e.g. +b a:spammer (a user with no account never matches) |
g | securitygroup | Members of a named security group, e.g. +b g:<name> |
y | reputation | A reputation-score range, e.g. +b y:<100, +b y:>500 |
r | realname | A real-name (GECOS) glob, e.g. +b r:*spammer* |
j | channel | Users also in another channel; an optional status prefix narrows by rank, e.g. +b j:@#staff |
s | server | Users on a given server name, e.g. +b s:irc.example.net |
G | geoip | A country code, e.g. +b G:<cc> (needs a GeoIP database) |
A | asn | An origin AS number |
b | banlist | Users caught by another channel's ban list, e.g. +b b:#staff (non-recursive) |
Acting extbans#
These gate an action for matching users rather than blocking their join. An +e exception with the
same letter:value cancels the restriction.
| Letter | Name | Restricts |
|---|---|---|
m | mute | Matching users below voice may not send channel messages |
c | blockcolor | Matching users may not send messages containing colour/formatting |
n | nonick | Matching users may not change nick while in the channel |
