Published Aug 4, 2026+8,850 added-3,265 removed

8,850 new domains were added to major block lists this period. 3,265 entries were removed. Steven Black Unified Hosts led the activity with over 5,000 new adds and more than 3,000 removals. EasyList and AdGuard filters showed typical churn, but the real action was in the removals column.

Umami Analytics: Mass Delisting

This period saw a coordinated removal of several umami instances from AdGuard DNS and Tracking Protection lists. Gone are umami.aigenerations.net, umami.spencerdevs.xyz, umami.subdavis.com, umami.syg.ma, umami.vidcore.net, umami.vidfast.pro, and umami.vidup.to. These domains were only added on August 4, so the reversal was quick.

Why does this matter? Umami is an open-source, privacy-focused analytics tool. Its removal suggests either an overzealous block or that maintainers got complaints from site owners using Umami for legitimate, non-invasive tracking. If you run Umami, you just dodged a bullet—at least for now. If you build anti-tracking features, keep an eye on how privacy tools are treated. Not everything with “analytics” in the subdomain is tracking in the surveillance sense.

Aniview and BMT Micro: False Positive, Fast Correction

aniview.com and bmtmicro.com were removed from both AdGuard Base Filter and EasyList. Both domains had only been listed for a day or two.

For developers and ad ops: If you saw sudden breakage of video ads (Aniview) or e-commerce flows (BMT Micro) earlier this week, it was probably this. These quick reversals show that list maintainers are watching for false positives, but also that legitimate infrastructure can get caught in the dragnet—even if only for 48 hours.

Generated Domains: Tracker Networks in Fast Forward

Eight new domains showed up on three major lists at the same time: AdGuard Base Filter, AdGuard DNS Filter, and EasyList. Examples include aarvfrxivnioe.space, 7cnpvpp5wfyf12.cfd, and 47b48d19d4.com.

What’s the deal? These are algorithmically generated domains, probably part of a tracker or malvertising network. The fact that three lists flagged them at once means detection is getting faster, but also that tracker operators are churning out new infrastructure at high speed. If you parse blocklists to identify C2 or fraud clusters, this is prime data.

Healthvot Domains: Medical Spam or Legit Service?

live-eu.healthvot.com and live.healthvot.com were both dropped from AdGuard DNS Filter. These look like medical or telehealth subdomains. They were only briefly listed.

For MarTech and compliance teams: If you work with health verticals, this is a reminder of how quickly legitimate services can get flagged—then unflagged—by automated or user-driven blocklist processes. Risk of false positives is especially high with medical domains, since scammers and legit providers often use similar naming patterns.
