Extbans are split into two types: matching extbans, which match on |
| 2 |
users in different ways, and acting extbans, which restrict users |
| 3 |
in different ways to a standard ban. |
| 4 |
|
| 5 |
To use an extban, simply set +b/e/I <ban> with it as the ban, |
| 6 |
instead of a normal nick!user@host mask, to ban or exempt matching |
| 7 |
users. |

Matching extbans: |
| 10 |
|
| 11 |
$a:<account> Matches users logged into a matching account. |
| 12 |
|
| 13 |
$c:<channel> Matches users that are on the given channel. An additional |
| 14 |
prefix of either @, %, or + can be specified to test for |
| 15 |
certain channel privileges. |
| 16 |
|
| 17 |
$o:<class> Matches IRC operators that have joined a class |
| 18 |
matching the mask. |
| 19 |
|
| 20 |
$r:<realname> Matches users with a matching realname. |
| 21 |
|
| 22 |
$s:<server> Matches users that are connected to a server matching the mask. |
| 23 |
|
| 24 |
$t:<tlsinfo> Matches users based on TLS protocol version and/or cipher suite. |
| 25 |
|
| 26 |
$u:<modes> Matches users having the specified user modes set or not set. |
| 27 |
|
| 28 |
$z:<certfp> Matches users having the given TLS certificate fingerprint. |
| 29 |
|
| 30 |
Acting extbans: |
| 31 |
|
| 32 |
$j:<banmask> Prevents matching users from joining the channel. |
| 33 |
|
| 34 |
$m:<banmask> Blocks messages from matching users. Users with voice |
| 35 |
or above are not affected. |
| 36 |
|
| 37 |
$n:<banmask> Prevents matching users from changing their nicks. Users with |
| 38 |
voice or above are not affected. |
| 39 |
|
| 40 |
$K:<banmask> Prevents matching users from using the KNOCK command. |
| 41 |
|
| 42 |
A ban given to an acting extban may either be a nick!user@host mask, matched |
| 43 |
against users as a normal ban, or a matching extban. |
