I hate to break this to you, but there's only 43 people on lemmy at all. We're all just pretending to be everyone, including you.
You aren't you at all, you're a constructed personality inside someone's mind with a lifetime of false memories and a thin veneer of "free will" to give you the illusion of being a real person.
That's one reason I love that there is no "karma" score on Lemmee. There's less incentive to recycle old memes, shill for upvotes, etc. But yeah for propaganda purposes, it can totally be done, probably is being done right now.
