I think you're overthinking it. She probably just has a lot of real people connections and drives the algo to meaningful interactions. When a ghost logs in, they don't know what to show so default to "general" spam which is just AI generated woman.
It reminds me of people who browse YouTube logged off: they see garbage, spam, rage bait, and sexy girls doing sexy stuff.
But I browse logged in and my carefully curated subscriptions mean I mostly get good quality, relevant recommendations, and almost zero rage bait or outrageous stuff.
The algorithm is not optimised for meaningful interactions, even 10 years ago i couldn't get it to even mostly show friends and family after fighting it for a week
The algorithm is optimized to show you content you tend to engage with. You couldnt get it to show you meaningful interaction because you didnt engage with it.
