Think about it: if a model/"influencer" posts a photo to social media, there has to be a disclaimer to any sort of photo altering or they face a fine. Given how many times you see the official picture vs. reality, I think it's smart. Not necessarily for body positivity, but to hold people accountable for posting fake realities.
Something like that is literally unenforceable. Also, would you want your tax money to go in paying people to investigate girls enlarging their boobs on Instagram, instead of, I dunno, hunting down tax evaders?
No - we need a law that says for every new law TWO OLD ONES must be removed PERMANENTLY - honestly if you don't know anything you see online could be FAKE you're probably a moron who deserves to be fooled
