As we have the same traffic policies as Google, we will remove sites that have invalid traffic. Recently, Google has revved up their policing of fraudulent traffic specifically because of the pandemic and its effects on ad rates. Google wants to get as many bad actors as they can out of the ecosystem to make sure ad rates remain as high as possible. So we remove sites with invalid traffic from our system in order to protect them from a Google Ad Exchange ban, which cannot be appealed. If you are able to show our Platform Quality team that you have not acted fraudulently and have taken steps to ensure that invalid traffic is no longer an issue on your website, our team will be happy to re-review your website.
