Kill Enforce

This enables kill protection for your nickname. With kill protection on, if a user tries to take your nick, they will be given one minute to change to another nick, after which they will be forcibly removed from IRC by NickServ.

Syntax:

/msg NickServ SET KILL {ON |QUICK | IMMED | OFF}

Options

On: User is given 60 seconds to change their nickname.
Quick: User is given 20 seconds to change their nickname instead of the usual 60.
Immed: User is killed immediately without being warned or given a change to change their nick.
Note: Improper use of immed can result in you not being able to use your nick.

See NickServ/Access for information on the proper use of immed.
