AFAIK it's impossible to smuggle it in a way that you can't be caught. Maybe the use of MD5 made it easier to see but if examined I don't think there's a totall

  Yes, he could have trained a network to recognize them and return memorized values. It would not be nearly as obvious. Solving this would require changing the contest so that it comes with algorithm and instructions only (no data files, entropy checks) and is trained by contest operators.

    This would also be very fishy to anyone who inspects the source code. Immediately they would ask "uh where did this giant file of floats come from?" One approach would be to write some handcrafted rules/features that look likecthey were plausibly a priori, but have the effect of memorizing the scraped data. (I don't know if this is actually possible.) User KaoruAoiShiho is probably right that any approach along would look out of place. Coupled with the fact that its removal would massively boost accuracy, it's hard to imagine how this would get past a curious reviewer. Perhaps peer review should be a component of the Kaggle process.
