Ninja looting isn't allowed because it's not supposed to be a part of the game. Sure you can find a different group and avoid the ninja looters, but they will continue to screw new people over. Some games allow scamming to a certain extent, but in this case you can't avoid it and the devs don't want it in their game so it is banned.
With pvping, you can just wait until that person leaves or go somewhere else to level, or do a profession instead, or ask for help. Revenge is possible, which adds to the element of the game. Some 80's are helping low lvls and maybe they kill you because they want their friend to get more quest mobs or be safe from any gank possible. After all, we can't communicate so why take the risk and let anyone live? I've been ganked, and I've ganked, and it's been frustrating and fun so I think it deserves to be in the game. If you get mad about it, then you are the one who is depressed and has issues and maybe this game is not for you. Get bullied, *****.
