Blocking trackers breaks sites and flags you as a target. So don't refuse — satisfy the cookie with garbage. This page first shows what trackers harvest from your browser, then feeds them a fabricated identity so the profile they build is worthless. Full functionality. Full privacy. Their system, against them.
Measuring how uniquely a tracker can pin you down.
Satisfy, don't refuse. The tracker wants a fingerprint and a cookie — so give it one. A fake one. The site works exactly the same; the identity it files away is fiction.
Different every site, different every time. Each poison persona is unique, so brokers can't stitch your sessions together — and can't tell the poison from a real new user.
Poison the cookie itself. Below, real junk cookies are written to this site right now — the tracker reads garbage.
