The reason for the pile-on wasn't for screwing up. It was for refusing to correct his screw-up after it was pointed out. Consider people who are declared legally dead but are still alive. If all it takes to fix it is showing up at a government office with some ID and saying "hey, look, I'm still alive", then a pile-on isn't deserved. But if the government workers all just say "the system says you're dead, and dead people can't come back to life, so there's nothing we can do", then they all do deserve to be raked over the coals until they change their mind.
