I have a very old Facebook account i haven't touched for no less than 10+ years. I had decided to just let it decay under the reasoning that old data is worse than useless to them, but now in light of Facebook announcing they'll take it all to train for LLMs if you don't opt out, i am unsure if to continue leaving that account to rot, or if to recover it, opt out, then doing the delete procedure. What would you say is the best choice?
