All unmoderated communities upvote easy to consume content. That's how group dynamics work. You either have to limit who can enter the community at all (which is what HN tacitly does), or what can be posted.

Are you suggesting that if I start a community called "pics_of_cute_cats" and a bunch of people come in and start posting military insignia, that's what the community wants?

Because it's certainly not what I, a member of pics_of_cute_cats want.
