Please follow SIM Rules.
But if you see someone breaking rules:
a) do not break rules yourself for revenge, because then you will be guilty of wrongdoing as well.
b) take it to the clan leaders. They have OOC and IC responsabilities for those clan members
c) If you are a clan leader, you must make an effort to solve the issue. If not, then eject the ‘troublemakerrs’ from your clan.
d) report things to sim owners when the rule-breaking doesn’t stop.
