I think there are different categories of "tracks". One category is marketing tracks, which include cookies, browser profiling, tracking scripts, etc. This is the one most discussion on HN is aimed at and most people find personally offensive but aren't materially harmed by. The second is legal tracks, which is exposure to harm from legal authorities for activities such as piracy, political activism, and various types of forbidden speech under different legal/national regimes. The third type is personal tracks, which I categorize as the ability for private individuals or groups to connect your online presence to your real self. That is the one I'm most concerned with, as internet users seem almost entirely unconcerned about it but it has far more potential to harm you than Google knowing your sexual fetishes. Nobody cares that they're exposing their real name and face to millions of people and it only takes one lunatic who decides your activities or opinions are worth trying to ruin your life to cause you a world of hurt.
