This is already happening on FB, just probably not using AI yet to automatically generate messages. In several FB groups I am in, messages appear from accounts that have been inactive for 5+ years, yet the 'owner' decided to suddenly come to life and start sending (usually) negative posts with regularity. This also happens with people trying to sell products (referencing a specific product by name/link in their message) using inactive accounts that have suddenly sprung to life again as a testimonial to how well 'it works'.
Sometimes they're hacked accounts, often of dead people who aren't around to complain to Facebook about it. It even happened to someone I know, his wife died and while he was sorting things out some scammer stole her account and he had to jump through a ton of hoops to prove to Facebook that she's deceased and to hand over the account to him.
