There are a bunch of great resources where GN'R fans will help you get anything you want for FREE as it was intended to be.
The site the OP is asking about makes a practice of selling recordings that were meant to be shared for free. Two recordings I made on the last tour are being sold on that site for $18 each which is ridiculous to me. The day after each show, the recordings I made were put up here and gnrevolution for free and I think it's awful that someone else is making a buck on it.
