That's interesting. There are a few notable groups of bad actors on HN but obviously the really good ones you wouldn't know about, which is a bit of a teapot. The lack of a downvote button on posts does stop a lot of attacks. Interesting write-up. I don't think the final exploit leads the way to a useable hack, but the journey says a lot.
