I think given the OP is a regular poster and they often post content from the same domains multiple times (each with a different article, with decent amounts of time between posts, i.e. ~1/wk), they probably just follow the content on these sites and "cross post" it to HN whenever they find something particularly interesting to them.

I can say personally (while I don't post on HN), when I share content in a community, it's things I find interesting, which often I see from the projects/blogs I subscribe to/follow.

So odds are OP is just someone with ADHD who finds this content useful to themself and people like them so they share new content from the site when they see it.

I did not elaborate on this for time reasons and because I don't want to make up unfounded accusations (astroturfing) against other users.

Just had a bad gut feeling with this particular post and content and wanted to comment on it (plus context).

Your explanation is nicer and I'll assume I was wrong here for it's better to assume good intentions.
