Dealing with spam
=================

Protecting yourself
-------------------
  /umode +R  -- only allow PM from users that have registered an account

or.

  /script install securemsg     -- install a PM blocker script
  /statusbar additem -after act securemsg window
  /sm accept legitimate_user    -- to accept some PMs from friends
  (see <https://scripts.irssi.org> for more information.)

or.

  /ignore * MSGS  -- ignore all PMs using Irssi's ignore system


Cleaning up
-----------
  /wc first_number last_number  -- will close all windows in that range

  Example:
    /wc 10 20

  To clean up your chat window (only for yourself)
    /script install sbclearmatch
    /scrollback clearmatch text/nick of the spam message

    Example:
      /sb clearmatch /!\ this chan....


Channel defence
---------------
(if you are channel operator)

Lockdown mode:

  /mode #channel +m  -- put your channel to moderated mode, only users
                        with voice (+) can talk
  /voice YourFriend  -- give YourFriend talking permission

or.

  /mode #channel +q $~a  -- make it so that people without registered
                            account are "quieted". Noone can see their
                            messages.
  /mode #channel +e *@gateway/shell/matrix.org/*  -- allow matrix
                            users to talk even without account (they
                            already have a matrix account)
