This period saw 8,525 new domains added and a whopping 17,898 domains removed across major ad and tracker lists. Steven Black Unified Hosts led the charge in both adds and removals. EasyList and AdGuard DNS Filter followed closely, each trimming over 4,000 domains. If your dashboards just lit up green, you’re not imagining it.

Bulk Rollback: The Curious Case of the 100execution.com Cluster

In a rare move, domains like 100execution.com, 10242systems.com, 1111runtime.com, 1214interface.com, 121basic.com, and 121macro.com were all added on September 8—and then removed from AdGuard Base, AdGuard DNS, and EasyList just two days later. That kind of quick reversal usually points to false positives, accidental bulk additions, or a correction after user reports. If you run infrastructure on similarly named domains, you might have dodged a support ticket nightmare.

Why it matters: If your app or analytics broke on the 8th and mysteriously fixed itself by the 10th, this could be why. For MarTech teams, these reversals show blocklist maintainers do listen—eventually.

yads.tech: High-Consensus Block

yads.tech landed on four major adblock lists at once (AdGuard Base, AdGuard DNS, EasyList, Peter Lowe's). This is the opposite of a false positive: consistent, coordinated blocking usually means either aggressive ad delivery, or a shared backend flagged by multiple maintainers.

Why it matters: If your media buying or ad delivery happens through yads.tech, prepare for breakage. Developers embedding third-party scripts should review dependencies. Four-list coverage means users are almost guaranteed not to see anything served from here.

Generated Domain Soup: The .rest and .cfd Swarm

An army of new domains with names like 221jn8219t6231zbom2z2b.rest, 8mrmb8n1z2zowboufw7ohyo2z9hjg.cfd, and 942cyhjqm3zwh5c.cfd were added to at least three major lists. The random patterns suggest auto-generated tracker or ad domains. This is classic churn: new domains pop up, get blocked after days, then replaced.

Why it matters: If you see these in your logs, it's a sign of persistent, automated tracker networks. For analytics teams, expect more short-lived, hard-to-research domains in referral and script data.

EasyPrivacy Pulls Back: 11nux.com Delisted

11nux.com was quietly removed from EasyPrivacy just days after being added. No mass list coordination here—just a single delisting from a privacy-focused filter.

Why it matters: For privacy tool vendors and site operators, this shows a willingness to correct course fast. If you rely on EasyPrivacy for compliance testing, note that blocking can be reversed on short notice.
