Another busy cycle: 5,521 new domains added, 1,078 removed. AdGuard DNS Filter and AdGuard Tracking Protection Filter led the pack, each clearing out nearly 500 entries. EasyList added 772 domains—zero removals. If you blinked, you missed a lot.

Short-Lived Blocks: 1.ccm-trk.com and Friends

If you track blocklist volatility, this one stands out. 1.ccm-trk.com and several similar domains were added to both AdGuard DNS Filter and AdGuard Tracking Protection Filter on November 6, only to be removed a day later. Same fate for 18723bnj.keyfy.fr, a.vital-health-path.com, and aa.tv.com.

Why does this matter? If your analytics or marketing stack sits behind infrastructure like this, you might have seen a one-day drop in signals, then a sudden recovery. It's a reminder: blocklist changes can be quick and noisy. Always check for temporary blocks before panicking about missing data.

alphwidget.com: The Brief Exile

alphwidget.com made a cameo on both AdGuard DNS Filter and EasyPrivacy, only to be removed on November 7. This is a rare case of a domain getting delisted from two curated lists simultaneously.

For MarTech teams, this is a signal that blocklist maintainers can and do reverse course—either after user reports or internal review. If your widget, CDN, or SaaS endpoint lands on a tracking list, swift outreach and clarification can work. Watch for similar quick reversals.

clickadu.io: High-Consensus Block

clickadu.io was added to four major lists at once: AdGuard Base, AdGuard DNS, EasyList, and Peter Lowe’s. This level of agreement across ad and tracking lists is rare. For developers, this means any functionality or monetization relying on this ad network is now likely dead in the water for users with mainstream blockers. If you're syndicating ads, double-check where your traffic is routed.

Pattern Watch: Another Wave of Generated Domains

Another batch of obviously generated domains landed in EasyList and multiple AdGuard filters: alppbalwrsyyw.online, ajtcqmlorjesx.site, accjcqrgpbpqj.space, and many more. These are classic signs of a tracker network using disposable infrastructure.

For anyone running detection or threat intelligence, this is both a pain and a clue: automation is driving both the creation and the blocking of these domains. Don’t rely on single domains for tracking or attribution. They will be gone by next week.
