I can agree with you on everything you've said except that bit about defining griefing. That is where the player's definition is irrelevant - if a player feels as though they are being griefed (for whatever reason, could be unrelated to PvP), they should first ask the player they believe are doing the griefing to cease and desist (politely as possible) and if that does not abate the behavior, the next step would be to request the support of a GM. Once it reaches that GM intervention point, a GM will determine if the behavior reaches that threshold outlined in the Code of Conduct guidelines and what the appropriate steps are moving forward. Otherwise, any player could say anything is griefing and we'd all be locked out of our game accounts 😅
