We've gotten complaints about this username, and I think I agree with them. Trollish usernames aren't allowed on HN, because they effectively troll every thread they post to. If you email us with a better name, we'll be happy to switch it over for you and unban the account, but I've banned it at least for now.

It seems to me this is actually of an example of it used in aggregate, removing pollutants across whole populations, rather than on the individual. I might also sooner say the lesson is if you can unambiguously use the metric to lift people up, that's good. You still have to be very careful about what that means.
