IGNORE
Usage: ignore <playername>
Ignore is the best way to deal with irritating players that keep sending you
unwanted tells. It usually makes the target very upset, so it should be used
with at least some consideration for other people's feelings.
Ignore only works until you or the target log out, after that it has to be
renewed. You cannot permanently ignore somebody.
No message about it is displayed, unless to the target, who will receive the
message "He/she is ignoring you" next time they try to send you a tell.
It does not prevent a player from sending notes to you.
