HN has the oddest karma system. I've seen submissions get 3 upvotes in the first minute and never another upvote.

Is that people looking at the new page and seeing/upvoting your post and then it falls off the front.

		That is many people's posts when I am reviewing new submissions.

That's probably the submitter's friends voting.

		It has happened to me and I'm not coordinating with anyone. I have also experienced very rapidly upvoted submissions flagged, then I notified HN admins, had the post unflagged, but after that time it was deep past page 12 and got like 5 more votes over 24 hours. I haven't seen the negative votes on submissions that people are reporting within this submission, but anyone who thinks HN isn't a target for myriad bad actors employing every means available to them to manipulate votes in whatever direction is a fool.

Ive been curating HN Arcade for a few months now. One thing I noticed is the vast amount of ShowHN games that get 5 karma points. I was thinking this was some sort of boosting system that low karma ShowHN posts get.
