Anti "Sexting" Technology Patented By Apple

Apple recently patented a technology that will help parents prevent their kids from sexting (using mobile devices to text self made erotica to friends).  Should a text contain certain words, the device would flag the message and prevent it from being sent. The content would either not be received by it's intended recipient or would be redacted. Also the child's grade level can dictate the filter level for the device. Apple's technology supposedly also catches abbreviations missed by competing technologies.
