Buying the Atziri Challenge

Is it possible to buy the challenge to fight Atziri in the temple of Atzoatl? Would everybody in that group get the challenge, even if they do not engage in actual battle with her?

And most importantly: Are there ways to minimize scam attemps from both the buyers and sellers side?

At first, yes it is possible to get the Atziri Challenge wihtout fighting her. You must be at least in the Temple. I fighted her several times and invited people for free.

Not to get scammed? I dont know what people pay for that, i invited people for free by asking in Global who wants to join.

POE Community develops too much in the direction of paying for everything, and headhunter of course..

Thank you for help.
