They aren't based on opinion. Everyone who regularly posts here knows the standards. And anyone who comes to the site comes for these standards. It's a good thing that approvals have gotten tougher, some of the old shit I had posted on the site embarrasses me now.
If people don't like the standards, they should start their own site, and post stuff there. Bandwidth is expensive, why on earth would a site that prides itself of quality host things that don't adhere to these quality standards?
People need to chill out and remember this is only a cover site. There are far more important things in the world to get upset about.
