9,297 new domains added. 4,179 removed. Steven Black outpaced everyone: 5,541 adds, 4,065 removals. EasyList and AdGuard both pushed over 1,000 new entries. Removals this period are unusually high, hinting at a correction binge or some false positives getting cleaned up.
Brightline.tv CDN: Blocked, Then Unblocked
cdn-media.brightline.tv and events.brightline.tv both landed on AdGuard DNS Filter on June 12, then were removed almost immediately. Brightline runs interactive CTV ads. The CDN here likely serves creative assets. For developers, this kind of whiplash means asset delivery could break, then restore, then break again, all depending on filter maintainers’ judgment. If you rely on third-party ad creative, this is your reminder: always monitor uptime and have fallbacks. See if cdn-media.brightline.tv is blocked.
Peter Lowe’s Purge: Old School Ad Domains Delisted
Peter Lowe’s list removed a stack of vintage ad tech: ads.powweb.com, affiliates.globat.com, clickyab.com, domaining.in, and advertipros.com. Most of these domains haven’t served real ads in years. Why does it matter? If your analytics tools or dashboards still track “blocked requests” to these endpoints, you may be chasing ghosts. Time to clean out those legacy exceptions and stop worrying about zombie domains. Check any of these on isblocked.fyi.
Consensus Blocks: The .cfd and Numeric Pattern Surge
Eight domains (like 2u1z7qmjvy1covuwg2rxkj3.cfd and 33apk.com) hit AdGuard Base, AdGuard DNS, and EasyList at the same time. All share a familiar shape: numbers, letters, and oddball TLDs like .cfd. While this looks like standard tracker churn, the speed and consensus are notable. If your anti-fraud or bot detection tools see a spike in requests from weird, short-lived domains, this is the pattern. Blocklists are catching these within hours. See if 2u1z7qmjvy1covuwg2rxkj3.cfd is blocked.
churnsbuyablealopias.cyou: Added and Removed in One Day
churnsbuyablealopias.cyou got added to AdGuard Base, AdGuard DNS, and EasyList—all on June 13. Then it was gone by end of day. Either this was a misclassification or the domain was a quick-burn operation that disappeared before anyone could care. For MarTech, this is a reminder that blocklist entries aren’t forever, especially for disposable campaign domains. Check the current status.
