Hacker News Reader

The third and most likely option is looking up the poster's HN profile and checking out historical comments made by the poster.

I guess the idea of looking a person's profile is foreign to me. Perhaps I should get into the flow of doing that.

I also read through the comment thinking.. deja vu? But yeah it was a copy paste from three weeks ago.

No automation. I had a feeling I'd read it before, so I checked the profile.
