Heads up to anyone using facebook or insta: you'll receive a notification about your data being used to train AIs. The opt out process is deliberately convoluted and you have to fill out a form to object. This is what I wrote in mine, and the objection was immediately registered as successful, so feel free to copy.
Masto reply bores, this is not a post on which to fart out your opinions about Meta or AI or whatever. So don't. I'm sharing helpful info for people who need it, not for you.
