Removes a specific global kline from the entire network. As with the akill command, any server that is split when you issue this command will not remove the entry.
Example:
/rakill lamer@pm02.digex.net
/rakill *@*.digex.net
If you set the global akill and now think it should be removed, you generally should remove it from the entire network. It's not a good idea to leave akills on other servers, because then they may not be noticed for a while and an akill may stay around simply because no one was responsible for removing it.
