I created my game and updated it a while ago, named Guess the Cricketer.

I updated it and added some new levels and linked to my admob account.

My friends downloaded the game but there are many people who can download the game and play it but if it is flagged due to suspicious behavior from the page owner, how can anyone download it? 

I also contact support but still no reply from them, Is this the contact support from Itch, not impressed by their contact support.

Why it is flagged as suspicious, what have I done wrong?
