Extbans

Extbans allow extending the standard nick!user@host into a different, more exteded ban selector. Usage of an extended ban is similar to a normal ban, except the following syntax is required:

MODE #channel +b $a:Horp

This sets a ban on #channel for any client logged into services with the account name Horp.

An extban can be negated by specifying a ~ before the kind of extban to be negated. For example:

MODE #tor +I $~c:#lamers

This will provide an invite exception in #tor to everybody not on channel #lamers.

Extbans can be used anywhere a ban-like mode is used such as: a channel ban (+b), ban exception (+e), channel quiet (+q) or invite exception (+I).
