The answer is to work on the accuracy of the process, not to throw up their hands and stop trying to ban scammers.

For this story in particular did anyone come forward to say that they had been banned that didn't participate in the scalping scam?

There's a culture of impunity out there on the internet were people think they can cheat the system and nothing will ever come it (think manufactured spending for example). Well, sometimes something does come of it. Don't do the crime, if you can't do the time.
