Can an editor or someone with more knowledge on how the site works comment here? It seems unreasonable for users to end up without the ability to post/comment (as long as they are not spammers or repeatedly posting extremely low content). I myself am I very new user to the site, and something like this would definitely turn me off. What is the criteria anyways?
