Have been stalking a competitor. One PBN that has been performing very well seems to have put a lot of effort into creating a fictional person/persona/author for a PBN, including: Guest posts (probably "guest posts") on other sites using the same persona, each article including a detailed and unique bio that has continuity with the fictional author's details, name, university/degree, life story, etc. Plus profile picture. A super detailed LinkedIn page for this fictional person Full Twitter account for said person, regular Tweets. Not just tweets to their sites, but also to niche-related articles About page + sidebar on the PBN have the same story, plus bio in each of the posts Backlinks back to the PBN with anchor text "[fake name]", especially toward the about page Plus a substantial amount of of profile page links on assorted websites (mostly niche related) about the same person Anyway, the actual question here: What is the plausibility of Google being able to understand/process a "person" across multiple sites? Could this give more legitimacy/power/authority to a PBN or other domain? I'm p̶r̶o̶b̶a̶b̶l̶y̶ going insane. P.S. Yes, I have considered that it could just be a real person. It's not. I've done a̶ ̶l̶o̶t̶ an excessive amount of digging and the person is definitely fake.
