6,592 new domains entered the blocklists this period, while 5,222 were removed. Steven Black Unified Hosts (ads + malware) saw the most churn, dropping over 5,000 entries. EasyList, AdGuard DNS Filter, and AdGuard Base Filter all logged over 1,000 additions each.
Charlton Media: A Whiplash Block and Unblock
charltonmedia.com had a rough 48 hours. It was added to EasyList, AdGuard DNS Filter, and AdGuard Base Filter on September 16. It was then promptly removed from all three lists the same day. For developers and ad ops, this is a reminder: even recognizable publishers can get caught in a blocklist slipstream if their domains are used for ad serving, or if a rule is too broad. If your reporting or integrations broke for a few hours, this is why. Expect some analytics blips.
Animesalt.cx: Triple False Positive Correction
animesalt.cx was added and then removed from EasyList, AdGuard Base Filter, and AdGuard DNS Filter—all in less than 24 hours. This kind of triple removal is rare. Most likely, a maintainer misidentified the domain as ad-related. If your anime platform stopped loading images or content briefly, this block-and-reversal was probably the culprit.
Highrevenueformat.com: Consensus on a New Player
highrevenueformat.com was added to four major lists at once (AdGuard Base, AdGuard DNS, EasyList, and uBlock Filters – General). When a domain hits multiple curated lists simultaneously, it usually means automated and manual review teams both flagged it as an ad or tracking endpoint. If you use this domain as a monetization partner, expect reach to drop sharply unless you pivot. Marketers: cross this one off your whitelist.
Creative.live.tktube.com: Temporary Exile
creative.live.tktube.com was added and then quickly removed from AdGuard Base, AdGuard DNS, and EasyList. This might have been a test of a new ad server or content delivery endpoint. The fast reversal suggests either a false positive or a quick change on the domain’s end. If you serve video or creative assets through subdomains, keep those naming schemes clear—otherwise, you risk landing on blocklists.
