> This transaction breaks a core promise using the internet: just because I visit a website doesn’t mean I consent to getting spam from it.<p>No it doesn't. There is no core privacy premise of the internet, and certainly not one that everybody used it signed up for.<p>I'm not condoning this behavior, but we're in territory that we don't have prior art for. It used to be totally fine for one shopkeeper to mention to another that he saw a customer looking for a particular item. When you do it at scale, the old rules don't apply.<p>If you think it's spam, hit the spam button in gmail and get rid of it. Use an adblocker. Talk to your congressman about data privacy and sharing laws, because we don't have anything that's effective. Frankly, continue to write Medium posts, because it raises awareness :) But, I disagree with the notion that this is a solved problem with bad actors, because we're in unknown waters.
