Microsoft adCenter Addresses Accusations of Illegal Pharmacy Advertisements

Microsoft says that the illegal pharmacies essentially hacked the system:

Based on our initial findings, we believe the advertisers noted in the report found a way to work around the verification process after being validated to advertise on Bing. These rogue advertisers manipulated the system by “hijacking” and/or misusing landing pages. Our internal teams are continuing to investigate how these advertisers sidestepped the policy.

adCenter is taking several steps to address the problem, including:

  • All pharma-related keywords have now been manually reviewed to sweep out any advertisers who are in violation of our policies
  • The editorial team is validating the claims in the report around “hijacking” and misuse of landing pages
  • The quality and editorial teams are reviewing our processes to document how these advertisers made their way onto our system. This documentation will likely lead to changes in process as well as product requests moving forward
