Reposts are ok after a year or so: https://news.ycombinator.com/newsfaq.html, as I explained before. Using a bot to submit would not be ok, but I don't think Tomte's doing that. As for "cover for posting divisive content" - if you think someone is abusing HN, please let us know at hn@ycombinator.com (as the site guidelines ask), and please don't make insinuations about it in the threads (as the guidelines also ask). We need to deal with abuse on the basis of evidence, not insinuation, and certainly not imagination, which such perceptions often turn out to be.

Tomte use to post a lot of good old stuff. I didn't notice s/he is reposting because the frequency is very low (6 months?) and not too many posts.

Also, it's generally interesting stuff, that raise the bar before I complain.

Edit: * and from a lot of different sources
