can someone clarity camp rules in a dungeon

[zaneosak]

I walk down to crusader camp in gukbottom. It's empty, nobody on track, the ph is dead. I wait around a little longer 10 mins, still nothing. I wait 23 mins nothing. I am sitting at the camp for 23 mins with nobody nearby or anything. I hear a person killing priest ph above me. Crusader ph spawns and I engage it, the person tells me this is camped and I said it looked vacant and I'd been here 25 mins. They said they did not have to be near the camp unless someone else wanted it and asked for it and if the PH is dead it's not a vacant camp.

I understand in LGuk that people camp bounce when its empty or low pop to get as many items as possible, I've done this myself but when someone comes in and takes a camp I left, I've always just conceded it -- or if i saw the place getting crowded, I'd make sure I was at the camp I preferred of the 2-3 I was killing.

Is there any written rule on this or should I be calling "crusader priest noble minotaur elder" on camp checks and its totally legal because I'm bouncing between them and keeping the PHs down? my understand was that I had to be there.
