It gets rather simple pretty quickly if you look at the site as a whole: accounts that repeatedly post like that one did have a destructive effect on the community, just like fire has on a town. We know it's mostly unintentional, but the flames don't burn less for that reason. We want the town to survive, so we can't let people do this here.

The analogy is good in another way too: we don't care what color the flames are, or what was used to start them. People sometimes complain that we moderate red flames more than blue and vice versa, but the issue is the same in both cases.

Thanks for the clarification, I respect your decision. Also thanks for what I imagine to be the rather thankless effort of moderating HN.
