Alter Aeon Rules of Conduct

Rule 4.3 - Thou shalt not harass people who don't want to PK with you

If the player you wish to kill does not want to play pk with you, you
must leave them alone.

While this seems obvious, PK players will occasionally harass non-PK
players in an attempt to goad them into doing something dumb.  Harassment
is harassment, and it is strongly recommended that if your potential
target doesn't want to play you should leave them alone.
