6,887 domain entries landed on block lists this period. 5,931 were removed. Steven Black Unified Hosts did most of the heavy lifting, but AdGuard DNS Filter, AdGuard Base Filter, and EasyList all crossed the thousand-mark for new blocks.

Springbot.com: A Marketing SaaS Gets a Reprieve

springbot.com was quietly removed from Peter Lowe’s Ad and Tracking Server List. The domain had only spent two days on the block list. For MarTech teams, this matters. If you use Springbot for marketing automation or analytics, your tracking pixels and scripts are now less likely to vanish into the ad block void. Expect more reliable campaign data—at least until the next review.

mtrtb.com: Four Lists Agree, One Tracker Down

mtrtb.com appeared on four major lists at once (AdGuard Base Filter, AdGuard DNS Filter, EasyList, Peter Lowe’s). That’s a rare consensus. If your app or site pulls scripts or trackers from this domain, assume coverage will be near-universal. Also noteworthy: tracker.mtrtb.com was just removed from AdGuard DNS Filter. Possible whitelisting for a subdomain, but the root is still radioactive.

ad.turn.com: Retargeting Giant Gets the Axe (Again)

ad.turn.com just joined Peter Lowe’s Ad and Tracking Server List. Turn (now part of Amobee) is a familiar name in retargeting. If you’re running display ads that route through this domain, expect higher block rates starting now. Time to check your fallback logic.

americanacademyofthermology.org: A Medical Society, Tracked?

americanacademyofthermology.org made it onto three major ad block lists in one sweep. It’s not your usual ad tech suspect. If you’re a developer for a medical nonprofit, this is your cue to audit any third-party scripts or legacy analytics. Legitimate orgs sometimes get caught in the net when their domains serve unexpected content.
