Dear reader, you may be missing a content blocker! 🙀 Please consider installing one to protect yourself, and your close ones, from manipulation and targeted malvertising! Personally I love both Privacy Badger and uBlock Origin (with EFF DNT Policy Allowlist) together, while AdNauseam alone would be more direct protest tool to oppose how the internet is nowadays. Android users may be better served by Rethink while for iOS there is AdGuard. Learn more about targeted advertising! PS. I am sorry if you are already protected and this silly EasyList targeting(?) script doesn't detect that, thank you for taking the steps towards a safer internet! 💜
