HN has a downvote button, but only for those who've engaged on HN for a bit prior to downvoting. It helps prevent abuse.
Same. It feels like a passive-aggressive elitism, and not simply an anti-abuse feature.
Given the site we're on, I don't have a problem as much with the elitism (I'm not the target demographic, after all -I'm older and not working in tech) as much as with the "passive-aggressive" part of the rhetoric behind withholding downvote capability.
Stories can only be flagged, which as I understand can lead to bans/losing the privilege if it's abused.
