Completely agree with n2n44. The review system on Envato is great, although slightly confusing and flawed in some small ways. Giving people the ability to put whatever they want will just flood the marketplace with crap. Items would be pushed off the front page within seconds or less. It would be very difficult for buyers to find items that are up to the quality standard, and personally, I wouldn’t even buy something from a site that has no quality management.
I find that it’s also a very valuable learning tool, when we create our own items, we might not always see the problems with it, especially if we’ve put so much time and effort into it, even if it’s the best thing we’ve ever made, that doesn’t mean others will see the value in it. I’ve been here for over 7 years, and about half of my items were all rejected at least once, usually more than once, and some never made it onto the market at all, which is frustrating, but it forced me to do better, now I’m at the point where I haven’t had a single rejection in years.
