Extended Bans

Extended bans allow different checks than the usual nick!user@host (hostmask) match to determine whether someone should be banned from the channel, allowing channel operators more flexibility and control over their channel's ban list. On DareNET, extended bans are of the form  . Where is one character (case sensitive) and determines the type of match that is to be used. If the tilde (~) is used, the result of the check will be negated.

The following types of extended bans are currently supported:

Account
The $a (account) type allows you to ban authed users who's account name matches the specified account mask.

If we wanted to ban all users who's account name contained the word joe, we could set the following $a type extended ban:

Channel
The $c (channel) type prevents users who are in a matching channel from joining your channel.

If we wanted to prevent users who are in channels with the word lame in its name from joining our channel, we could set the following $c type extended ban.

Realname
The $r (realname/gecos) type prevents users with a matching realname from joining your channel.

If we wanted to prevent users who had the word bot in their realname (gecos) from the joining our channel, we could set the following $r type extended ban:

Shared bans
The $j type allows sharing channel ban lists.

For this example, the name of our channel is #ourchannel and we want to use #shared ' s channel ban list with our own. So, to do this we could set the following $j type extended ban:

Now, whenever a user tries to join our channel, #ourchannel, they'll be checked against #shared ' s ban list in addition to our own ban list. If a match is found in either ban list, the user will be prevented from joining.

NOTE: The shared channel must not be in +p or +s for this to work

Text bans
The $t (text) type allows channel operators to specify words (wildcards supported) that will be blocked if the user's message or notice to the channel matches it.

Let's say we wanted to block all channel messages and notices that contained the word damn, regardless of the user sending it. To do this we could set the following $t type extended ban:

Negation / Reverse logic
If "~" is prepended to the type of an extended ban, then the result of the comparison is negated. In other words, it will have a reversed effect.

Let's say we wanted to allow users to join our channel ONLY if they're already present in #darenet. To do this, we would set a $c type extended ban, by prepending "~" to the type flag:
