Firebog.net is a long-running collection of Pi-hole compatible blocklists, maintained as a community resource for over a decade. For a site that serves this kind of utility, the technical foundations are strong: valid HTTPS, DNSSEC, and a fast CDN. There are no malware flags or blacklist appearances, and the domain ownership is clearly documented.
What should you watch out for? The site lacks a privacy policy and terms of service, which is standard for a non-commercial hobby project but worth noting if you're concerned about data use. Firebog.net reviews from the blocklist community are generally positive, and the operator provides contact info. The only oddity is the absence of Wayback Machine history, but that may be intentional. Overall, this is not a scam or fake site — it's a legitimate tool with a proven track record. If you're asking 'is firebog.net safe?', the answer is yes for its intended use.
