It'd be nice to eliminate them, but the official SE stance on hunt marks is that they're open world content and whatever you do with them is kosher unless it involves actively killing people using the hunt mark in question or resetting the thing to let more people arrive. Heck, we've even had someone with so little of a life that they have to self-destruct on Forgiven Gossip spawns to ruin SS rank attempts.

Until something about the system or SE's stance on it changes, the best we can do is to keep our chins up, control the flow of information so that the most possible people can make it there, and endorse hunt strategies that make it possible.

Folks shouldn't join in on early pulls either, is the thing! It takes five minutes for them to solo an ARR S rank and twenty-five for an HW S, so it should by all rights be a cooperative effort that involves people not swinging on the things until the established pull time or until it drops low.
