Agreed, but there's also possibility that it was found using some password script. One thing about large organizations is that if many people from many different groups need access to the same account (like a twitter account) the password is often simple, seldom changed, and far too easily provided to non-authorized users.
Fully agree though, that it's going to be found to be a small group of kids with short-sighted liberal beliefs behind it. And I expect one of them will be in the Ohio town where the restaurant resides.
