I've started digging into the archive.org history of several of the blogs on the Russian tampering list - started with the one I best remember seeing before (blackness-by-your-side). Hustleinatrap, ghettablasta, and swagintherain (possibly others) were part of a reblog cluster with this blog.
Some observations so far:
The blogging style seems to mostly consist of pulling stuff from other social media/news sites that lots of people are likely to agree with, and adding vehement comments.
It is obvious that there's something "off" about the linguistic style when you pay close attention. How many actual Black Americans do you know that don't understand the use of definite and indefinite articles in English? (Speaking of which, "hustle in a trap" already stood out to me, but I assumed it was a Tumblr dialect mutation before this.)
Some of the work they were doing was very subtle, and burying it in a hail of posts that mostly everybody agreed with was a very good cover strategy.
There's a weird aesthetic similarity between them.
Some of these blogs have what look like SEO posts about random topics in between the political ones. How do you do, fellow American humans?
