We take this kind of abuse seriously, so please email us at hn@ycombinator.com if you ever see anything like it. The community is pretty sharp at detecting this kind of organized behavior though, especially with the combination of new accounts all about the same age with few or no prior contributions. We spend a lot of time on anti-abuse software to catch these as well.
