On reddit you see hundreds of dormant accounts that will suddenly become active at the same time and all attack a particular person saying anything contrary to the hive mind. So they will not post or comment for 3-5 years and suddenly will all attack a user at once then the accounts will get deleted. Most of these are programmed with a back date of origin but on nostr I dont think you can do that.
So what im thinking is that someone is planning a troll army. One person can seem like lots of people and try to bend the narrative as they do on reddit.
just a thought
