This script defends against forced joins, such as from irssi's fuckyou.pl or
|
|
from channel forwards, as well as forced parts, such as from the /remove
|
|
command. You can configure certain behaviour using the options under
|
|
"plugins.var.perl.antifuck.*". Configure rejoin-on-/remove with the
|
|
irc.server_default.autorejoin and .autorejoin_delay commands.
|
|
|
|
Running "/antifuck part" will close all forcejoined channels and part them where
|
|
appropriate.
