HN comments more than a day old cannot be downvoted
Looks like this is a recent change. I'd be curious what bad behavior it prevents. I first saw it in the context of the massive spotify thread, and it seemed very surprising that some comments could be up/downvoted, and others only upvoted.

<edit>I took a look. I see that the comment was in fact informative - even if the message is very worrying for anyone who might want to use spotify</edit>
All of this is temporary, and downvoting imo is going to cause more anger than it does promote the reasons for HN existing.
