Tomte has >100k karma (that seems insanely high, but also a 10+ year-old account), and a plethora of reposts in his submission history. If you wanted to juice-up your karma (I can't fathom why someone would bother doing this), it seems like simply reposting popular submissions from previous years is a very easy way to do that (if it was popular on HN in years past, then it's likely it would again). I'm not saying that's Tomte's motivation. This would also result in interesting/popular submissions resurfacing again and again, which anecdotally I can say I've seen quite a bit on HN. I don't think that's necessarily a bad thing, but perhaps it can get tedious for some. For example, I had not read this post before and found it useful/interesting.
