so basicly: if someone ks you, and do not listen to you, what do you do? pls help
Well, in these cases, checking to see if you could get hold of a GS could be an ok move. GSes usually cannot do much about KS issues except inform of the rules and hope that players will stick to them and use common sense in general. There ARE some cases where the attention of a GS (if one is available) can be useful though, the main one being when the KSing player is not responding.
A player not responding can usually be attributed to one of the scenarios below:
1 - The KSing player is a bot makroed to farm a certain area. The bot will usually not answer to queries, and if it does, answers are usually generic and nonsensical. Setting up bots is illegal.
2 - The KSing player does not speak English.
3 - The KSing player couldn't care less.
In the case of scenario 1, a GS could come to the scene to try to discern whether the KSing player is a bot or not and take whatever measures deemed appropriate (ie recording a video and reporting the player - will not solve the problem immediately, though). If you have the software to record video yourself, you should do this in case a GS is not available so you can file a report yourself.
In the case of scenario 2, a GS could try to find a way to communicate with the player to find out what language the person speaks and then find means to inform the player of the rules in his/her own language.
As for scenario 3, well...the question is whether the player is abusive in his/her way of KSing. On one side, no one can claim mobs, so it is usually a case of the strongest being in the right. But if a player constantly KSes the mobs you are working on, also after being told repeatedly to please stop doing that, we are moving into the area of harassment. To prove this, video/screenshots would be needed if actions are to be taken in retrospect by GMs after a report is filed. A GS is usually quite powerless in these situations, as nothing will be going on when he/she arrives on the scene and it will be a "she said vs he said"-situation. This is why a GS will more often try to PM the involved players, explain the rules and leave it to the players to make up their minds whether they want to follow them, use some common sense, or carry on with their territorial fights. That's when the guide in the OP comes into work...
