Another busy period: 10,802 domains added, 3,712 removed. AdGuard DNS Filter and Steven Black’s Unified Hosts led the charge again. EasyList and AdGuard Base Filter both saw over a thousand new domains. Removals spiked, mostly from AdGuard’s various filters.
Relayto.com Removed: False Positive, Fast Fix
a.relayto.com was added to both AdGuard DNS Filter and Tracking Protection Filter on November 3, then removed less than 24 hours later. Relayto is a SaaS platform for interactive documents, not ad tech. This is a classic false positive—likely triggered by automation or overzealous rule matching. If you run analytics or embed third-party content, take note: even widely used SaaS endpoints can land on blocklists and then get cleared just as fast. Monitor user complaints and test flows if you depend on these platforms.
ComicBook.com’s Ad Server Gets a Reprieve
aa.comicbook.com was briefly blocked by AdGuard DNS Filter, only to be removed within a day. ComicBook.com is a mainstream entertainment news site. Blocking their subdomain likely broke ad delivery or analytics, prompting a quick rollback. For MarTech teams at publishers: subdomains tied to ads or analytics can get swept up in broad rule changes. Have a plan for rapid response when core domains are suddenly blocked.
High-Consensus Block: Bagave.com
bagave.com was added to four major lists this period: AdGuard DNS Filter, AdGuard Tracking Protection Filter, EasyPrivacy, and Peter Lowe’s Ad and Tracking Server List. When a domain lands on this many curated lists at once, it’s usually a clear signal of widespread tracking or ad activity. For developers, this means blocking is already in effect for most privacy-focused users. If you rely on this domain, expect breakage.
Pattern Watch: The .cfd and .site Domain Flood
EasyList added a flood of random-looking domains ending in .cfd, .rest, .site, and .space. Examples: 6blw4whh5lc83lji3y7q2l83m.cfd, aafrjewsszwiv.site, abxcsiahbpqmw.space. Most appeared on three lists simultaneously. These are likely programmatically generated domains used for click fraud, popups, or tracker evasion. The takeaway: if you see traffic from these, it’s almost certainly junk. Block, ignore, or escalate as needed.
