When you send others a paper document or a letter, your private information or some sensitive contents will be disclosed along with them. To protect those contents from being leaked, people can black out the unwanted parts with a wide black pen. Even in the digital era, people also have to face privacy disclosure when sending pictures or PDF files to others.
