This module adds the new channel mode +y. It prevents non-regged nicks with non-alphabetic chars from joining a +y channel. A blocked nick must register to nickserv or change the nick.

Certain types of spam bots like to use non-alphanumeric characters in their nicknames (|^{}) etc. This module adds a mode that will block anyone who is using an unregistered nickname with those characters from joining the channel. If your network is being bothered by this bots, this module will definately provide some relief!
