"the obvious culprit"
but I will point out that the messages immediately before that post have mysteriously 'gone missing', and the post editing to make the post link to 'future' HZ posts points to the obvious culprit...
Nope, though from my own forensic investigation I can understand how you might jump to an erroneous conclusion about who was behind it. I won't spoil the fun of رجل من وقت by divulging my own theory about how it was done, but it didn't seem to involve editing the post (needless to say, the possibility that it might have been done that way freaked me out, but I eventually concluded that no actual hacking was required).
Actually, now that you mention it, you were one of my chief suspects (in part because my theory requires that the perpetrator be more than a little obsessive ;-) ). Still are--I'm not easily sidetracked by what's possibly a pose on your part. But if it was you, congratulations, nice work.
