I also got banned for downing and tying up a witch. Like what other legit reason do I need other than it being a witch? The entire town even rallied up to get the loving witch.
Were you to actually read the server rules, you might find that out.
The fact that you're making up rules to punish players for particular play styles (as demonstrated above with your ridiculous obsession with regulating and monitoring RDMs) is further proof that you don't understand the problem. Players need to roleplay that out. If you have someone come up to you and start attacking you without any immediately understood reason, you should defend yourself and if you die, you die. That's exactly how it would play out in real medieval times. God didn't magically zap people for killing peasants in a particular manner. You should let players handle policing of behavior.
Think about how killing people in a City RP works. They are not banned from the server. They are labeled criminals and are hunted by the players roleplaying as policemen and subsequently jailed. Perhaps you should consider including such a system rather than resorting to banning people. And have judge/warden occupations that can rule to release prisoners early or extend their time in prison as the admins see fit.
We don't even
have an occupation system. Further, in a City RP, if you die, your character is not permanently dead, in most that I have seen.
Think about it this way: You are playing in a D&D campaign. Suddenly, the DM declares "Rocks fall, everyone dies!" Is this fun? Do you think that is valid?
