Yes. Any of the really heated political threads on this site are full of posters like this. I don't want to dox anyone, but since at least 2019-ish I've found posters that spend hours a day posting huge amounts of content in large bursts on this site.

COVID was ridiculous as I presume a lot of anxious people were stuck at home able to do nothing but post.

Does this account for them reading the article though? There are pre-existing opinions that could be easy to rapidly post based on topical discussions but here it also has to be considered the time to parse technical submissions.

They read this article, called out a specific discrepancy then commented on a paper on Arxiv in a 70-odd word post then the same minute another 70-odd word post on a different technical post. Maybe like you suggest they're just wired differently.

Yeah, there are plenty of very online people who are great at just posting things and doing the minimum amount of diligence to contribute their thought. Like I said, just hang around in any of the high energy threads on this site and you'll see a lot of it.
