Except that slamming people for not knowing what to do is what every other platform does. If you post what you had for lunch today on some band's Facebook page, the post is obviously going to be deleted. If you were to post something about a new game coming out on /r/askreddit it would be deleted because that is obviously not the right place for it. You have to assume that there is a baseline level of knowledge for anyone using any website or else you will get stuck explaining every single thing which is not an good use of time. Nobody should have to be told that "You only should add tags that relate to your post". That should be assumed knowledge. Every other site has knowledge that is assumed, and steemit's will have to be that you should never tag posts with tags that don't relate to it's content.
