For the longest time, the YC application included the question "What was your greatest (non-computer) hack?". They have always liked people who think of ways to work around existing systems. So it's no surprise that their response was positive. Also, all the principals are ex-founders, mostly engineers, who totally understand hacking culture.

Sadly, it looks like they took that question off the application though.

That question is still there, it lives in the founder profile.

Except this was a computer hack. So technically wouldn't qualify.
