Does section 230 shield them from ads they select for display? Ads are not randomly hosted by random people and if you visit a random page those people uploaded, you see them. Google selects the ads they want to show you on search results, before youtube videos, or on third party websites. There's no "we don't know what that might be" going on at all -- they are running sophisticated algorithms to optimize the impact of those ads. Is that still be covered under section 230?
