Having a hard time with people saying "if you don't like it then do...". KS has been a bad part of this game since I joined in May 2004. Some don't realize this is CHEATING and should be looked at as cheating. People who cheat shouldn't be able to dictate how a person of character plays.
If the person doesn't understand how KS works let them know what they did is wrong. if they do it again I would report them to the server admin and see what he/has to say.
One thing people can do is ask if they can help....
