When I leave a one star review in marketplace (because the world won't even load and I can't get a refund) the review bot recommends I leave feedback on aka.ms/marketplacefeedback but if you go there that website no longer exists.  If you aren't even going to have a marketplace feedback website, take the boilerplate off of the store. The last thing you want to do to a pissed off one star reviewer is increase their frustration by sending them to a dead site.  Just insult to injury, man.
