I almost wrote about this but I think Diana is simply an "article spinner." I think she's a person because she has left a different comment on two or three of my posts because she agreed with something in my story.
I think she uses AI apps to "spin" about 5 or 6 of the same articles in different ways. Then, after she clicks publish, she goes and highlights a bunch of articles, claps, and leaves the same comment and simply changes the name of the person.
And she or he is aware of who the folk are that read back. He or she probably keeps a list. I don't think "Diana" is a bot, just a person gaming the system.
