Go to policy center first and read exactly why its caused...could be they are Monitoring traffic could be code issue could be another program issue. At least read the message don't beat the trump worried here and there. In most cases, as it has happened and does happen and will happen alot......its invalid traffic. origin of user vs unique users vs page views vs ad impressions vs clicks / per day...maybe you didn't do something somebody else did. No way of knowing. Right now just keep the traffic flowing and add new content or rotate it as if nothing happened. I think around about 3rd they will remove it from most people.
