I have seen his posts shortly after it happened, there was a topic about it, all of his posts still existed and all of them were edited in this way. I was curious and checked two far apart posts and there was like 6 hours of time inbetween the time stamps of the edit. I believe cmp checked and said that all the edits were made from his account. I'd say he literally manually edited over a 1000 posts as some kind of weird attention seeking endeavor, who knows. His account wasn't deleted then, guess that happened later.
