The posts don't seem excessively low quality at first glance - indeed a lot of the submissions get at least some discussion / votes. But it does seem like the kind of content that's simply copy/pasted from maybe other aggregators, or selected from previously submitted HN content.
The account is 12 years old, so I'd expect it would have been booted by the mods at this point if it was undesirable.
tosh, is your posting automated?
It is not automated but I concede that hn might have become an excessive hobby over time (wait until you see the log of articles I don't submit though! so there is also some curation on my side).
It basically is as simple as: I stumble over something interesting, thinking one thing that would be even better than this is a whole discussion about it, submit, crickets or discussion actually happens.
edit: many (most?) submissions (like this one for example [0]) are actually based on something I read on hn so there is some tree traversal and recursion going on as well now that I think of it.

If you're interested, I'd definitely recommend taking some time to step away from browsing all day.
- Lots of links in bio
- High frequency of posts
- Reposting popular content
Hope you have a good vacation!
