Super-SEO-Spam-Suppressor

What the blocklist targets

Super SEO Spam Suppressor, abbreviated SSSS in the README, is an anticapitalist blocklist aimed at websites that abuse search engine optimization tactics to spam web searches with data pollution and security risks. The README describes the covered categories as content farms, scrapers, copycats, generative AI outputs, scams, advertisements, malware, and what it calls useless wasteful garbage in general. It is built to work with uBlacklist, the browser extension that filters blocked sites from search results, but the project also ships many other formats. The README opens with a blunt complaint about the state of search, citing reporting that Google's search functions have degraded since 2019 and arguing that the commercial drive to optimize every interaction has harmed other search engines whose indexers crawl content written for Google's algorithm. The author frames the list as an attempt to escape what they call continuous capitalist coercion and attention theft, and suggests pairing it with a social media blocklist because the large tech platforms all play the same game. The tone is opinionated and political, which is unusual for a technical list, but the practical offering is a plain domain blocklist that a user can subscribe to with one click in several clients.

Formats and where it works

The project's main strength is the range of output formats it maintains from one source of domains. The README lists uBlacklist, AdBlock Plus, Hosts, Dnsmasq, pdnsd, Unbound, Mastodon, and Fediblockhole as supported shapes. uBlacklist and AdBlock Plus formats support match patterns, expressions, and regular expressions, while Hosts and the DNS tools support domain and TLD level blocking. The Mastodon and Fediblockhole formats are scoped to the Fediverse and cause instances to defederate from blocked servers. Each format links to a raw file in the repository, and the uBlacklist path includes a one click subscribe link, though the README notes subscription links must be enabled in the extension for that to work. The DNS formats can be used with Pi-hole or a resolving server, and the README flags a known issue that Firefox's DNS over HTTPS option can bypass the computer's hosts file ruleset. For a self-hoster, the Dnsmasq, pdnsd, and Unbound files provide drop-in configuration. The breadth means one contribution can protect a browser, a network, and a social account at the same time, which is the project's stated reason for maintaining so many parallel formats from a single source. The README also notes a known issue that Firefox's DNS over HTTPS option can bypass the hosts file, a caveat that pushes privacy minded users toward the DNS or browser extension formats instead.

Contributing and aggregation

The README gives two ways to contribute. A technical contributor clones the repository and adds one domain per line in dot txt files stored under the sources and domains folder, with subfolders and dot txt files organizing blocked sites by category. Comments using a hash and markdown files can add context and references, and the update script cleans a pasted full URL into a domain. Because the hosts format does not automatically block subdomains, those must be added explicitly for compatibility. Top level domains can also be listed and will be blocked by Dnsmasq, adblockers, and uBlacklist. After changes are pushed to the sources folder, GitHub Actions generate new versions of the blocklists automatically. A non-technical contributor can simply open an issue with the URLs to add or remove, grouped by language and category if possible. The README also documents an import path where external lists are added to a file as a name and URL pair, downloaded twice a day, cleaned, and merged. The project borrows from many other blocklists, and the README credits each source with its own license, drawing on work from projects such as uBlock Origin dev filter, Search Engine Spam Blocklist, and several anti-AI art and anti-spam lists, among others.
