I have a post (https://developer.apple.com/forums/thread/825224) from a day or so ago. I got a nice reply asking for some followup information, but I'm not longer authorized to view or reply to the thread. The weird thing is I often do see the thread for a second or two, then the page gets replaced with "Unauthorized. Access to this place or content is restricted. ..." without me doing anything. Sometimes I can see the page for longer, but posting a reply usually results in an error (and frustratingly, the contents I write disappears).
