POW captchas aren't actually captchas, it's just hashcash (IE make sure the person reading the content is using as much or more compute as you are serving it so they can't DOS you either on purpose or accident.) We stopped needing it for a while because compute and bandwidth grew really fast while serverside software mostly stayed the same.
