2,742 domains were added and 2,125 removed across major block lists this period. The busiest filters: AdGuard DNS (+944/-679), AdGuard Base (+870/-701), and EasyList (+865/-703). Several domains were dropped almost as quickly as they were added. Meanwhile, a few new entries drew rare cross-list consensus.
Rapid-Fire Removals: Six Domains In, Six Domains Out
A cluster of domains—like 1m75n265ptqhpoztjn8c.rest, 1or8z2l9xx8cmioeg79y7iqou64xi5quitbcm.rest, and 2g7366rbvvrzkj46piiuwx167t.rest—were added to AdGuard Base, AdGuard DNS, and EasyList on June 23, then removed from all three just days later. This isn’t common. Removals often mean a false positive was spotted, or the domains were so short-lived that blocking them was pointless. For devs: If your legitimate service is suddenly inaccessible, it could be caught in this kind of whiplash. For tracker operators, your churn rate might need work.
High-Consensus Blocks: outerwords.com and correctedcode.com
Two domains—outerwords.com and correctedcode.com—landed on four major tracking lists at once: AdGuard DNS, AdGuard Tracking Protection, EasyPrivacy, and Peter Lowe's. Rare agreement like this usually means the domains are either running widespread tracking scripts or have been flagged by multiple researchers. If your analytics or marketing stack pings these, expect a lot of missing data.
The .rest and .cfd Pattern: Churn and Burn?
Many new additions in EasyList this round use randomized subdomains on .rest and .cfd TLDs. Examples: 1gqh7qw8hii19koi.cfd, 1ibh8q6m1qfn62gk7c7.rest, 3h4jh45l96127e6.rest. This is classic disposable tracker/malvertising behavior, using generated names to dodge filters. If you rely on hostname-based allow lists, expect more noise from these TLDs.
124technologies.net: A Real Company Gets Noticed
124technologies.net is now blocked on three lists (AdGuard Base, AdGuard DNS, EasyList). This domain is used by a known MarTech vendor. If you’re using their SDK or API, you may see increased ad/tracker blocking, leading to incomplete reporting or broken functionality for users with aggressive blocking.
