For an HN audience, the "How Bestspotting cheated" post on Kaggle may be a better place to start: https://www.kaggle.com/bminixhofer/how-bestpetting-cheated

It's an odd way to cheat too, if they realised they had data from the validation set, couldn't they have over-trained a model with the validation set in the training data?

Agreed, this actually happened in the buildings ASREA comp. the data was found online.

Yes, that would have been harder to detect if it is allowed. My understanding is that for a kernel competition (like this one), you can't use model weights that you've trained outside the kernel. Oddly, I can't find a rule explicitly prohibiting it.

Is it me, or has the HN user-sphere changes significantly this year.

I feel as though comments are less informative, more judgemental, and chalk full of emotions.

...as if a younger crowd of users has started using it.

Have the older-wiser HNers started using another site?
