Guoh sent a DNP request about a year ago and then removed it. Many of the posts are in this limbo where they should be okay to post (no active DNP), but they already exist in the system so they're duplicates. His Tumblr, which was the source of these posts has also been nuked - I exported a bunch of images before the blog went down but now I'm not sure what to do with them.
I found a couple of comment chains where people were discussing this last November, but nothing came of it: post #1382156, post #1382157
