Copypasta is a chunk of text shared across the internet, which becomes a kind of random text meme. It might be a bunch of letters, numbers and punctuation marks used to make a face. It might be an obscenity-filled rant from a supposed Navy Seal. Or it might be some text in an image, which reads something like “Goodbye Meta AI… Ido not give Meta or anyone else permission to use any of my personal data…” The content doesn’t matter, because it’s classified as ‘false information’ by the platforms and is ignored.
If you don’t want social media to use your data for training AIs, go to the Settings and Privacy options and make your wishes known there.
