I'm going to go out on a limb here and hazard a guess that you're not a writer.
The thing is, we learn from our mistakes. As a writer, I get more from well thought out constructive criticism such as Anonymous offered than I do from being told how awesome I am. I'm good enough to have gotten a couple of things picked up by a publisher, but it was listening to readers telling me what I got wrong that helped me improve.
My editor doesn't care about my delicate feelings. Editors are brutal, but if I listen to them, and keep my whining to a minimum, I wind up with a truly outstanding book. That's because there's no room for the thin-skinned when it comes to writing. And if Jashley13 isn't complaining to me about being flamed, then I think you can rest easy and not castigate Anonymous for doing what every writer hopes for.
