As the system doesn't currently allow me to respond to a report directly, I must state here that I disagree with what you stated in your report, and feel that you may be overestimating what you should be expecting from free community feedback, which as you must remember is driven entirely by peoples' good will and willingness to give others' feedback and advice.

The critique you received discussed each major section, identified things you did well, and areas for you to work on. The "Mark as Unhelpful" option is reserved for cases where people have put in no effort, and have only provided empty platitudes.

In the future, keep in mind that the person giving you feedback is not receiving anything from you in return, and so you can only expect so much.
