Playing devil's advocate here... university systems feel like a great place to poke around recklessly like this. Especially when presented publicly. Any holes in the system that enabled such ease of abuse should be patched up. I don't know the author but would guess these hacks would never be used "in production" or with any system expecting to earn money. They're pretty blunt about how hacky it all is, and they don't sound happy to have done it.
