Do you know the difference between targeting based on data and having the data? I can show you an AD based on ur search I can't buy ur search history and see you looked up hentai.
We sent you this ad because we know you like hentai and “we asked Google to look through their data and show ads to hentai watchers” is a distinction without a difference when it’s equally uncomfortable that Google is looking at this information as it would be for Google’s clients.
