What are the "rules" for camps that can contain multiple spawn locations/placeholders

[Delacroix]

I try to respect people's camps, because I've seen how shitty some people can be when they don't, and it's very irritating. Standard camps make sense and I think it's just takes basic common courtesy to not be an asshat and everyone will be happy. But what about camps such as the Hunter/Forager cycle in TT? Or Quillmane? Camps with placeholders and multiple potential spawn points.

Can someone claim the "Quillmane camp" while all of their placeholders remain off limits regardless of where they spawn? Can someone do the same with the cycle in TT? Or is it more of a first to engage type of ordeal in situations like this?
