My publication is one of the ones these criminals have included in their footer. They are not only scraping the content, as you point out, but they randomly insert synonyms into the articles that end up making the content nonsense to avoid getting caught for plagiarism, one assumes.

It's also not a new shtick. It/'s happened before: https://medium.com/marketing-communications-leadership/how-to-lazily-yet-effectively-rip-off-my-content-f5913e44ad08

New (probably) rip-off artists. Same crime. I wonder what they get out of it.
