How do we even know the story is at all truthful? Maybe someone who still works there did something stupid they couldn't recover from and is now blaming it on "an ex-admin" to make it sound nice.
Is your first assumption that people only post their first assumptions? WTF dude. There are plenty of people in this thread already ready to tar and feather a completely unknown person. I'm just trying to point out that we don't actually know anything about what is going on.
