Hello,
I don't know what do you mean by restricted list of URLs or how can I send you the list of blocked ads (I had blocked a lot of ads before as well)? The way I find those ads is by searching the texts which are present in the screenshots sent by users. For example, from the attached ad image you can extract the search term "pedidosya promociones en farmacias". For me the result brings 3 ads with the exact same image but with different sizes. Isn't that enough to try to reproduce showing those ads?
More information concerning how this problem started: firstly, the problem happens on Android app, used library version is 19.2.0. There were no app updates for at least 2 weeks, no AdMob or related setting was changed for a long time. Just out of the blue, on March the 2nd I started receiving a lot of angry emails from users who cannot close interstitial ads, also 1-star reviews and high uninstall rates (also a high rate of in-app purchases of ad-remover which is still ugly). The problematic ads where from different countries and from different devices, I couldn't see any pattern. I don't see a lot of people having a similar issue in this forum, so I am guessing we were a victim of some kind of A/B experiment.
App's MAU is about 1 million. Currently all the interstitial ads from AdMob are disabled. AdMob's interstitial ads were the main source of the app's revenue. I haven't received any resolution from AdMob support.
Regards,
Narek
