Jesus fucking christ. He fucking ran MD5 on some shit he pulled down from a web crawler.
Over-training a model on the validation set would be a lot more "brilliant", and even that is a dumb script kiddie level hack. Maybe finding an algorithm that computes weights s.t. the preimage of the training algorithm on the training set matches the result of training with truly random weights using the validation set. That could be a "clever hack". And even then _brilliant_ would be.... a real fucking stretch.
