Unnecessary Censorship refers to the practice of adding censor bleeps, mosaic blurs or black bars to source materials that were neither profane or explicit to begin with. The bleeps are typically dubbed over words to make it sound as if they were explicit. Mosaic blurs and black bars are placed over people, objects, or text to make it appear as if they are covering up pornographic or explicit material.
