The "feature" you mention - having a post visible to you when logged in, but apparently not visible to others - is a long-standing feature. Posts from some sites are "dead on arrival", the mods having determined that posts from those sites are usually poor, and the better ones will be reported by other sites which are not proscribed. I agree that it would be nice to have, somewhere, a complete list of features, but this is not a new one.
