Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for enhancing user interaction with an interface. Methods include determining, using a first evaluation rule, a likelihood that content depicts objectionable material. The content is passed to rating entities for further evaluation based on the likelihood that the content depicts objectionable material. When the likelihood that the content depicts objectionable material is below a specified modification threshold, an unmodified version of the content is passed to the rating entities. When the likelihood that the content depicts objectionable material is above the specified modification threshold, the content is modified to attenuate the depiction of the objectionable material, and the modified content is passed to the rating entities. The rating entities return evaluation feedback indicating whether the content violates content guidelines. A distribution policy is enacted based on the evaluation feedback.
