Disinformation, carefully used, would be my first line of investigation.

As an aside, the Humble Bundle Choice releases were being reliably leaked. Until this month ... https://redd.it/1bqpp2l - so I suspect HB did the same, and carefully distribued info to establish the mole's identity.

Thanks for the reply. The school is trying to go about a "normal" investigation processes. I'm trying to do due diligence before suggesting a full on disinformation route to the principle. It's getting messy though.
