Thanks, this is valuable information for us.
But everything that is in the rules is described here.
- I'll tell you my story.
My app is in a garbage dump with ads cut out and a lot of money. It's not my fault and I can't control it. Therefore, these hacked apps often give a lot of requests for ads without impressions and AdMob often gave me a FREEZE.
-How I solved the problem.
Removed old ad blocks and created new ones with ads. Introduced severe restrictions on advertising requests. I request it in the code no more than 60 seconds. Introduced a restriction on requesting ads after the start, the player can only ask for ads after playing for 60 seconds or more. It saves you from bots.
After that, within a week, the restriction was lifted.
I got tired of doing this and connected mediation, which has its own AdMob, now this is their problem and their eCPM is higher than admob gives.
I advise those who earn more than $100 on their game not to be lazy and insert meditation.
Below is a screen shot of US figures.
