Sitting in the middle of someones camp etiquette

[ld420]

So some rando shaman logs in and sits in the middle of my pull zone so i cannot root rot any longer, or risk them getting their ass beat by my rooted mob as they are KoS, essentially preventing me from proper pulls. I repeatedly asked them to please move, but they never answered. Am I in the wrong if I root a mob near them and they die? I mean its beyond rude to just sit in the middle of someones camp spot, or am I wrong about that?
