Xp mobs outside of the room you're sitting in (not even sure if you can claim xp mob camps, room or otherwise) are fair game. In fact, the best thing to do is to get a rotation going, and simply stand where the mobs will spawn. They'll all spawn in sequence- let someone try to take your mobs when you know the spawn timer and you're parked over each mob as it spawns. That's the only real way to "claim" xp mobs tbh.

Or send a tell. If you can't claim the mobs via rotation, and the person isn't very kind, the only thing you can do is leave. You could submit a petition . . .but xp mob camp disputes are lame, and you're only wasting the staff's time. Just go somewhere else.
