The other day i ran a very limited amount of traffic from Popads as i was bot testing a specific category. The stats looked ok but i spotted something that i want to confirm. I noticed that most of the traffic was being reported as screen resolution 640x960, Popads tracking macro was sending this as 800x600. On the face of it that looks ok but digging deeper, No iPhone has a resolution of 800x600 and only the iPhone 4 and 4S have a resolution of 640x960. The problem is that the iphone 4/4S doesn't support IOS 11 and from my research it stopped at IOS 7. When i look at the ISP's they are all genuine so am i right in thinking this is actually a BOT and maybe the sites linked with these hits are using traffic surfing networks which may spoof certain browser and OS versions. The bot test i had focused on Click Bots but this seems like impressions bots to me. Anyone have any other theories?
