Alter Aeon Rules of Conduct
Rule 7.6 - Thou shalt not summon other players without their consent
Being summoned when you aren't expecting it can be an irritation at a
minimum, and can result in very bad consequences (including death) in
other cases. You should never summon someone unless you have their
permission.
There is a clear and obvious exception to this rule - you may summon
pk or ppk characters, within certain restrictions, if you intend to
player kill them:
You MAY NOT summon a pk to a dangerous monster or area if there's a
chance that the monster or area will kill them instead of you killing them.
A ppk player MAY summon another ppk player to a dangerous monster
or area with intent to kill them.
Note that you can use the 'nosummon' command to make it impossible for
other players to summon you.
