Bad idea: you know how sometimes people have a "me but a bot" account? Where they've trained a gpt3 bot on their original posts, and have it regularly generate a fake post by them?
Why stop there? Train another bot on the first bot account's output. And another.
See how many bot accounts it takes until foonebot7 is just posting "floppy floppy floppy floppy floppy floppy" 24/7
