Like I said, it was a long time ago. August 24th, 2008. Before I met my friend who drilled this stuff into my head. Take it up with him. XD (But you'll have to figure out which of my many Facebook friends this person is, first.)
Seriously though, I didn't even realize I had it. Never view any profiles, nothing. So yeah. Again, it was a long time ago.
Regarding why the hell it didn't revert if it's no longer an option... I have no idea.
