It looks like if you are in the post revision screen and compare a post to itself, which is dumb in the first place, but still, you will get this hidden gem. I hate to be that one guy, but it just doesn’t seem like the refined WordPress CMS experience and reminds me more of a Sub7 feature which is a old school back door trojan program. It even spells the words slowly as if typed in real time, scary l33t h4x0r stuff.
I can imagine some intern at a company scared to death once the “self destruct” pops up on the screen and then goes black with some Matrix style quotes below.
