Control the entry of inappropiate data by users

Hello, I have a question about the data entered by the users. How can I prevent that users enter inappropiate or harmful data (for example, pornography)? Is there any feature that filter the content if it is innapropiate?
I know that we can configure the app for some data must be first authorized by the admin before show it public. But maybe exists an automated and practic way that could deny an user enter that kind of data.
I appreciate your answer!

I don’t know of an automated way to handle this. Maybe several admins that can periodically approve content. Or design your app in a way that a user needs to first earn enough reputation to post certain things, or all people to flag a post and automatically hide it.
