Over this three-day stretch, block lists saw 1,034 new domain entries and 22 removals. The big movers were AdGuard DNS Filter (+343), EasyList (+339), and AdGuard Base Filter (+323). No major ad or tracking list had any removals, but the Online Malicious URL Blocklist cleared out 22 domains. Let’s look at what matters for your analytics, tracking, and MarTech ops.

Malware Purge: 22 Domains Dropped

The Online Malicious URL Blocklist removed 22 domains. No detail on which, but such removals usually indicate those domains are dead, reclaimed, or false positives. If you had analytics or scripts breaking due to an old block, check if your service is working again. This kind of clean-up is rare these days—most lists just grow.

MIUI’s RUM Endpoint Hits EasyPrivacy

apm-rum.inf.miui.com was added to EasyPrivacy. This domain is used for Real User Monitoring (RUM) by MIUI, Xiaomi’s Android skin. If you’re developing apps for MIUI or tracking analytics via this endpoint, expect increased reporting gaps for users with EasyPrivacy or anything that consumes it (AdGuard, uBlock Origin, etc). If you rely on RUM for performance metrics, time to check your dashboards.

Consensus Blocks: The .rest and .cfd Swarm

A set of suspiciously random domains got blocked on three major ad lists at once: AdGuard Base Filter, AdGuard DNS Filter, and EasyList. Examples include 4mtj1r9x5gnbo4u7.rest, 693o1wu7266lzxowx4xv.rest, and 9gg33gxuvvw4q9o.cfd. These look auto-generated—likely disposable ad or tracker infrastructure. For developers: if your test or tracking infra uses similar naming patterns, you risk collateral damage.

EasyList’s Grab Bag: Analytics, Coupons, and Oddballs

EasyList added a mix of domains, including amgarnirenic.qpon and assetscramsdryinid.qpon. These are likely related to coupon or affiliate schemes. If you’re running promotions or user acquisition via lesser-known coupon platforms, check your traffic and attribution—your links might just have disappeared for users with common blockers.
