Out of curiosity, how often do you detect vote and flag manipulation events?
I assume the accounts in this flagging event were otherwise active and "healthy"? On Reddit, accounts are created years in advance so they seem legitimate when put to use for nefarious purposes later on.
Alas, I can't answer that because HN is under constant attack by people trying to game it and I can't satisfy your curiosity without satisfying them too.
