Watchlists and Blacklists

Databases like EFF’s Atlas of Surveillance and Privacy International’s Surveillance Industry Index cataloging government and corporate monitoring tools.

Resources like OONI and Freedom House reports that track which privacy and circumvention tools are blocked in different countries.

Community-maintained filter lists (e.g., EasyList, EasyPrivacy, Peter Lowe’s) enumerating ad and tracker domains to block at the network or browser level.
