Sounds like some form of fraud to me. What's the difference between that and simply forging a ticket to an event instead of buying one? Or forging a currency note?
OK, the better example from further down. You realise your badge lets you into areas of the premium tour, it opens all doors, not just the ones you paid for it to open.
And even if it is fraud of some kind, the bar for charging someone with fraud (instead of just suing for damages) is fairly high...
