Colossus SSP Faces Alleged ID Fraud
The piece centers on the SSP Colossus, acquired by Direct Digital Holdings (DRCT), amid serious allegations of ad fraud. Adalytics claims Colossus sent mismatched user IDs to The Trade Desk during bid requests, implying fraudulent activity in prebid auctions. The report outlines a four-step process showing how Colossus could mismatch IDs through BidSwitch and trading partners, with The Trade Desk reportedly not including Colossus in buys by default due to quality concerns. Google DV360 had previously turned off Colossus for quality issues and later re-enabled activities after Colossus reportedly nuked its cookie pool. Colossus responded by filing suit against Adalytics. The article also notes Colossus’ focus on multicultural audiences and its 2023 revenue of $112 million with a 13.5% take rate, along with auditor resignations at DRCT and related delisting risks. The discussion touches on broader industry implications for identity, measurement, and fraud in programmatic ad tech.

Chrome CrUX Ad Metrics Target MFA-Style Page Quality
In an opinion column, Shirley Marschall examines two ways that premium ad inventory can degrade: contamination (bad actors entering the supply chain) and convergence (independent publishers adopting aggressive monetisation due to economic pressure). She cites Adalytics' research showing MFA inventory appearing in PMP deals, and a case from T-Mobile's Noam Gissis where a premium news site crashed browsers, raising questions about MFA red flags emerging outside MFA sites. The article highlights Google's new experimental CrUX ad metrics (Ad Count, Ad Density, Ad Weight by CPU, Ad Weight by Network) as a browser-based measurement layer for inventory quality, which could help advertisers assess user experience beyond supply path.
