I don't know how they to do it, but they certainly need to be picky, and it's difficult finding an abstract feedback inside a wall of text, that is part of a long thread, where the main argument switched to some real world political issue (which is more important than any game, but still, this shouldn't be the place to post those)
Also they can't promise that one or the other issue will be fixed. I can understand that.
Still, some way of marking/sign/logo would be useful, that they noticed one problem or the other. Even a stickied raw internal list would do.
What we have now is just words like these (search for "feedback" on that page)
