If you notice inappropriate reviews, report them and we'l take care of it. People have definitely loss access to G&N for comments like that. We can't see everything, but when they're reported we take care of them.
With regards to submitting headshots vs. glamour shots, everyone gets access eventually (500 posts and 3 months as a member), and you're close to that now. Admins review early access applicants to determine if they are at a point where they can contribute to the forum based on their body of work - that is, they're already shooting G&N and have images to contribute now.
That's the best explanation I can offer.
