We are very cognizant of how big of an issue this is for all publishers. Although, we have always done our best, we acknowledge that we have struggled in the past to track down and eliminate redirects. Unfortunately, every case is unique and complicated to track as the bad actors purposely make their malicious actions difficult for DSPs and Exchanges to detect. What we were able to do in the past was completely dependent on the information that we were provided. And at times it felt like whack-a-mole with us getting a bad ad blocked on one DSP only to find it appear in another shortly after.
We continue to investigate every reported redirect fully to determine the responsible party. We also give publishers the correct ad partner to contact, if it has been reported to us by mistake. We know that if it is hard for us to track down the source of the bad ad, then it is also difficult for our publishers. When we find ourselves to be at fault we admit it and contact our demand sources directly to fix the issue immediately. When we find that we did not serve the ad, we pass the information along to the publisher so they can take action. We have a dedicated ad quality team that is available for bad ad support if you visit http://www.sovrn.com/support/.
Today, we now have the tools to proactively protect publishers and to better investigate malvertisements. We recently partnered with Confiant to scan every single OpenRTB bid response looking for malware and redirects. We can align only OpenRTB demand partners upon request, allowing the publisher to be confident that sovrn will not serve any malicious creatives. The downside is that there is a marginal revenue trade off which is not ideal for everyone. This is available upon request.
We are always available at http://www.sovrn.com/support/ to help set this up for you, discuss your options or answer any questions you might have. Please contact us and we can give you full rundown on our new partnership with Confiant and what it means for you.
We are dedicated to eradicating these ads from our exchange and appreciate your help and input in doing so. Please do not hesitate to reach out to us. We are reaching out to each individual publisher who has posted in this thread to be sure that we find the necessary solution and eradicate the issue, whether it be from sovrn or another ad partner, or both.
Thank you again for all the great input regarding this issue. We are always striving to get better and hearing your experiences helps us to do so.
