OISD is a domain blocklist that prevents devices from connecting to unwanted or harmful domains. It aims to reduce ads, lower malware risk and enhance privacy, prioritizing functionality over blocking. The big list blocks ads, phishing, malvertising, malware, spyware, ransomware, cryptojacking and telemetry or tracking, while a separate NSFW list blocks porn, adult, shock and gore domains. Support for HOSTS and domains syntax was discontinued starting January 1st, 2024.
