Report/Flag Button for Marketplace Items

I have recently discovered this:…validated=true

It was $20 at some point. now it is at $700.
First: Why is this allowed?
Second: I would like to have the possibility to flag such content.
A price should not be chosen arbitrarily, but according to the cost of the creator and some win%. Not just 20% creation time and 700% win.
The point is: Customers are potentially scammed, because you cannot refund it. There is no support according to comments and the quality of the product doesnt seem to be that good aswell. Such content should not be allowed on the marketplace.
