to urge facebook to ban all forms of porn on there site

As a mother to a three year old child facebook has not listened to my concerns as to the load of porn on there site. I have reported up to 100 photos due to pornographic content or sexually explicit content as per there guidelines but they refuse to look at there own guidelines on this subject it disturbs me that so much nudity and pornographic material is on this site now two years ago the site was better now it keeps going down hill please urge president obama and Marc zuckerberg to clean up this site and ban all forms of porn and nudity its not right for an already busy mother to have to do marcs job for him
