Your character will not be tagged an outlaw if you loot a corpse of a player under next circumstances:
-if you are in a Chaos Zone;
-if you or your fellow party members have killed the character;
-if the corpse in question belongs to your clanmate and they are online.
Please be aware that the corpses that lie around currently do not carry the information about the killer and thus looting them in a non-chaos zone will mean a bounty on your head.

Character with level lower than 11 is not allowed to loot player corpses at all. An attempt to do so will result in a tip-like message which explains the rights-and-wrongs.

You will no longer be marked as a criminal if you attack a criminal.
