When uploading an app to Play Store, it gets tested on Google’s test device infrastructure for a “Pre-launch report”. By testing it is usually meant that an automated script (aka Robo) performs random actions and clicks on an app. And naturally, some of those clicks land on the ad.
So far this hasn’t been a problem for me because I am yet to be approved for Marketplace. But in the further app updates, the test will be run again and will result in unwanted ad impressions and clicks, basically bot traffic. To avoid this, Google suggests that publishers set up their ad networks to filter out the IP’s of Google’s test devices and not serve Demand ads to those, but I haven’t found the possibility to do so in MoPub.
How should this situation be handled? As far as I know, pre-launch reports cannot be disabled. But I also don’t want to violate MoPub’s policies and be banned for inflating impressions and views.
