To that end, I've actually been avoiding the downvote and flag button entirely. It's handy to close off an avenue of admin retaliation, but on a deeper level I feel like the reflexive race to downvote people you disagree with is the "game" part of gamified engagement.
Besides, if an HN user says something horrendous, I feel like other HN users deserve to know the kind of company they have on this site, instead of tone-policing it under the rug.
