There might be a correlation, but I doubt it's a strong one. Maybe there just aren't that many unique accounts here, and this isn't a particularly mainstream site. There are reasons to be turned off of Hacker News that go beyond the layout.
Imageboards can have pretty low-tech and annoyingly obtuse UX as well but trolls adapt and abound because there are no user accounts and they know they have an audience. Most of the trolling I think i've seen here has been done through throwaway accounts, so who knows whether or not those are sockpuppets of existing accounts or people showing up from /g/ to have some fun?
