I want to develop an app where users can upload an share images. I am planning to integrate a disclaimer which says that it is prohibited to upload images which contain crime, sex, insults etc. Furthermore I want to implement a report a user button where multiple reported users get blocked. But most of the people do not care about it. My question is: Is there an image processing algorithm or a webservice that detect such images? How do all the other social networks handle this problem? It is impossible to do this by hand.
