6 SILENCE is similar in many respects to IGNORE, except that it is
7 server-based. What this means is the server will never even send
8 you messages from anyone you have SILENCEd, whereas it will with
9 IGNORE, where your client is responsible for filtering the messages
10 out. This has the advantage of not bogging your client down with
11 excessive data as it tries to filter out messages.
13 The default behavior is to SILENCE a nick!user@host pattern, and
14 if such a pattern is not passed as the argument, it must be prepended
15 with a plus ('+') to be added to your silence list. If a pattern is
16 prepended with a minus ('-'), it will be removed from your silence list.
17 If you only specify a nickname, you can list the patterns in the
18 silence list owned by that nickname. If no arguments are given, your
19 own silence list is displayed.
