There is a rumor going around, supposedly started by a facebook engineer (working via the new name Meta) who claims a new AI is in the final stages and it's sole purpose is to cover up genocide. This new AI tracks the style and frequency of posts from users, so when they vanish it can auto generate new posts that make the person indistiguishably look like they are still alive, including aging, education progression, the whole 9 yards.

People using social media will be fooled by the AI and will not notice the crowd is thinning out and they probably won't figure it out until they themselves "die suddenly" or hear a knock at the door, and they probably won't figure out what happened to everyone on Facebook even then.

Think about it - for what other reason would facebook want to fake the fact that account users have vanished? Sure, you could say it's all economics and fake accounts might be possible to convert to cash, but if fake is all they want, they would not need to go through all the trouble of imitating real people, it would be easier to simply fake up new members from scratch. In fact, it would be a LOT easier to simply generate entirely fake people than to have to deal with millions of families saying "How is my deceased loved one still posting"? Unless that won't be an issue because entire circles of association are to be wiped out, like the communists in Russia did it -

After the bolshevik revolution, Russian communists managed the vanishing of people by killing entire families and all associates, so no one asked questions. This obviously took a lot of work because they had to figure out how to delete people by killing everyone without making it obvious while still maintaining a population that could carry forward. Nowadays, AI is going to assist in carrying out such a program with precision and it will be easy to do, because nowadays all people do is flick their phones, they, outside of work, don't actually know anyone face to face. And AI, which studied them constantly, can just keep right on posting and "maintaining relationships" without the disappearance ever being noticed. An AI can also manage family communications so meeting "face to face at christmas" can be delayed forever.

The people being deleted can simply be replaced by immigrants so neighborhoods don't empty out, in the end there will be only a few non-threatening bottom feeders left, musing at how all the homes around them filled up with foreigners. Relatives who happen to drop by will be left hanging, wondering what the hell happened, like the disappearance of "wally world" and if they raise enough of a stink, they can be eliminated also.
An ai that continues posting, creating perfect fakes of people that have been vanished is now probably the biggest threat we face, I believe it will happen and genocide will never be easier.
