This period saw a net purge: 6,268 domains added, but a massive 25,004 removed. The top three lists by volume—AdGuard DNS Filter, EasyList, and AdGuard Base Filter—each cut nearly 7,000 domains. Steven Black Unified Hosts added 3,193 but still removed 4,085. Removals won the week.
Bulk Rollback: 1000replicas.com and Friends Get the Axe
If you blocked 1000replicas.com, 102cryoura.com, 1080zero.com, or 111rexor.com in the last 48 hours, your blocklist just changed its mind. All four domains landed across AdGuard Base, AdGuard DNS, and EasyList, only to be yanked almost immediately.
Why should you care? These sudden removals usually mean one of two things: a false positive, or a short-lived campaign that fizzled. If you rely on blocklist coverage for analytics or compliance, don't assume new entries will stick around—especially if they look like throwaway infra. Always check before hardcoding exceptions.
Tracker Churn: High-Consensus Blocks for Algorithmic Domains
Several domains with algorithmic names—like 74i6p9yieo9b1y2g1nxu.rest, 5bf6m8tye77hw7nmzrgl.rest, and 22kolrqjyr15835g.cfd—were added to three major ad lists at once. These generated-looking domains are a common signature for tracker networks or click-fraud infrastructure.
For MarTech and analytics teams, this means automated tracker generation is still alive and well. If you see user traffic from similar domains, odds are high they're short-lived and will be blocked quickly. Don't get attached.
SaaS Lookalikes: 2048instances.com and 52dispatch.com Flagged
Two new entries, 2048instances.com and 52dispatch.com, hit AdGuard Base, AdGuard DNS, and EasyList in one sweep. Both names could pass for SaaS microservices or infrastructure. Their rapid blocklisting across lists suggests either abuse or tracker deployment piggybacking on "business-y" branding.
Developers using third-party services: double-check your dependencies. If you white-label or embed external scripts, review what gets loaded. A surprise block can break user flows or analytics overnight.
