Aurora Mining is obviously a ponti schema. Just check the profit they promise and compare it with competitors and you shall come to that conclusion as well. If not, do a picture search on the employees and you will notice they are generic pictures not existing ... even ignoring the fact that the company address is not a reliable corp as well (you can rent in the address ATM ...).
So please, don't make other people go in there just to make profit by your reference. You're helping in a scam (being illegal in most countries) ...
