Ad filtration can be adjusted by marking off the “filter mature content” square in app settings. 

That way we exclude adult ad categories in an application for each separate ad network. Networks that don’t support filtration of categories can be fully disabled. Thus, filter enabling can affect an app’s fill rate.

Enabling COPPA doesn’t affect ad categories. This setting switches on COPPA support for your app in every integrated network account. It also disables all networks that have no COPPA support, which can also reduce fill rate. 

Please, keep in mind that after enabling “filter mature content” creatives that do not suit the app’s age ranking may still be displayed. Unfortunately, category moderation mistakes can happen on the network side. We also cannot modify the content of networks integrated via your personal accounts (Admob, Meta Audience Network), because Appodeal doesn’t have access to those accounts.
