Alter Aeon Rules of Conduct

Rule 7.7 - Thou shalt not pick up other players without their consent

Being picked up, like being summoned, can be an irritation at a minimum,
and can result in very bad consequences (including death) in other
cases.  You should never pick up someone unless you have their permission.

Like summoning, you may pick up pk or ppk characters, within certain
restrictions, if you intend to player kill them:

You MAY NOT pick up a pk and drop them near 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 pick up another ppk player and drop them near 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 pick you up.  If you cannot be summoned, you can not be picked up.
