11,160 new domains entered the blocklists this period. Only 78 domains got a hall pass and were removed. Steven Black’s Unified Hosts led the charge with 6,781 adds. EasyList and AdGuard Base Filter each pruned 17 entries. As always, the removals tell the real stories.
A Short Stay for adimise.com
adimise.com was added to both EasyList and AdGuard Base Filter on June 9. By June 10, it was gone from both. That’s a 24-hour cameo. This kind of whiplash usually means one of two things: either the domain was accidentally flagged, or someone convinced maintainers it was a false positive. For developers, this highlights the importance of catching list changes early. If you operate a legit service and get caught in the crossfire, you’re at the mercy of list maintainers’ response time.

A Batch of Overnight Removals from EasyPrivacy
Six domains—1cros.net, 4251.tech, a1webstrategy.com, alpha1trk.com, catsunrunjam.com, and aaxwall.com—were all added and then removed from EasyPrivacy within one day. These weren’t random removals. The pattern suggests a bulk error or overzealous addition. If you rely on EasyPrivacy data for analytics QA, double-check your block monitoring. Sometimes rules are reversed as quickly as they appear. False positives do happen, even on major lists.
Coordinated Blocking: 2o7.net and the Old Guard
DuckDuckGo Tracker Radar added 2o7.net, 2mdn.net, 33across.com, 360yield.com, and 3lift.com. These are not new players. They’re fixtures of the tracking and ad tech scene. The mass addition to a privacy-focused list like DDG’s means Tracker Radar is tightening its net, perhaps catching legacy domains that slipped past earlier automation. For MarTech teams, this could explain a sudden drop in third-party tracking coverage—especially if you still rely on these domains.
Pattern Alert: The Case of the Numbered Domains
Eight newly blocked domains appeared on three major lists at once (AdGuard Base Filter, AdGuard DNS Filter, EasyList). Examples: 489t8e5xt649ryji.rest, 25solutions.net, 311ingreenhouse.com. The numbers and word combos don’t look like real brands. This is a signature of generated domains, often used by tracker or ad fraud networks. If you see these patterns in your analytics, it’s time to audit your traffic sources.
