Dive Brief: 

• A multimillion dollar ad-fraud operation exposed by Telemetry is still in operation, according to the online security firm.
• Telemetry believes around 100,000 of the nearly invisible video ads are still sold each day — much less than at the scam's peak, but still significant.
• Brands like Unilever are still paying for fraudulent ads, partly because nothing is done to the sellers of the ads besides a website being added to a blacklist, and that move is easily circumvented by simply creating a new site.

Dive Insight:

Like Telemetry executive vice president Geo Carncross explains in the video, as long as the operators of these ad schemes continue to receive a check, there's little motivation for them to stop. Even if they are exposed for the scheme, why would they halt if money is still rolling in? The intermediaries that are still paying for invisible ads need to be educated on what they are purchasing before any real progress can be made.
