YCombinator fraud rates

I would be careful to discern between fraud and police state allegations of fraud. Aaron Swartz is clearly the latter and it at least deserves to be mentioned in the article.

I agree that Y Combinator is good at filtering out fraud - and I'd argue that's why they have so many high value companies - which would invalidate your argument that these balance out. Why do you think they're good at filtering and why do you think the effects balance out?

Wonder what the false negative rate is.
