While the dark web has a bad reputation due to its links to illegal activities like drugs and pornography, it also has sites that provide useful services or allow for anonymous communication. For example, a number of email providers are available on the dark web, and some even offer encryption features to help keep your messages private. Another useful site is ZeroBin, which lets you send encrypted files of any size.
Some of these sites are completely legitimate, such as domain dark web links service providers and email providers. Others, such as those that offer whistleblowing platforms, can run afoul of repressive governments and may be subject to censorship in some countries. Still others fall into the gray area between purely private and illegal, such as social media sites and websites where people can buy and sell drugs or weapons.
