Why are you assuming that the hosting locale is even relevant? I’m not going to ban anything, but if @phire’s idea was law, it would probably ban anything advertiser from choosing which ads to show you based on your personal data. It’s irrelevant where the ads or site is hosted, I assume. If ads from foreign countries don’t target individuals, their ads would be legal. If ads from foreign countries, or from the US, use your posts to choose which ads they think you’ll engage with, that wouldn’t be allowed under @phire’s proposal. Is @phire’s suggestion confusing?
