alt Hacker NewsIt seems like the kind of thing I would naturally post if I came across it, so a bunch of submissions over 3 days makes me think a bunch of people saw it and when they saw it said huh, I will submit to HN.
I think that makes more sense than some spam campaign for this.
I’m wondering how this is possible. Usually when you submit something that has been already posted recently, HN will upvote the existing post instead.
