Rule #7 -- Offensive/menacing behaviour and names
Players who behave in a way that is perceived by the arches as offensive, obnoxious, menacing etc. do so at risk of losing access to the game for a time, ranging from days to years, possibly forever, and perhaps even for the site(s) you are calling from.
Looting is NOT illegal, but repeatedly "stalking" or ruining the gameplay for another player in a longer period if time, might qualify for harassment.
Harassment is not tolerated.
Keep in mind that minors may play the game, and that in some people's view, swearing, sexually explicit expressions etc may be damaging to their development into adults.
