I think the initial post would be fairly advanced for a 
machine-generated post.  That means significant time and effort - which 
means significant money.  And the question then is, why?

A technical Usenet group might have around 50 regular members, several 
hundred lurkers who are mostly read-only, and be google-groups searched 
by a few thousand.  There is no advertising, and thus no income.  So 
there is nothing to be gained by making such machine-generated posts in 
Usenet.

Compare that to insta-snapo-book social media, with millions of users, 
valuable advertising, ranking and "liking" systems, and a far more 
gullible readership.  Some areas of these social medias are dominated by 
bots making posts and liking each others posts to modify rankings and 
generate artificial advertising income, or to push their political 
agendas or crazy conspiracy theories, perhaps even as an attack on 
another country.  It is a different world entirely.

You get the odd vandal that uses automated software to make Usenet 
posts, but these are mostly absurd posts.  And there are a few cases 
where people have made Usenet poster programs for fun, to imitate 
particularly annoying posters.

The original post is much more likely to be homework than a bot of any kind.
