Rot13 turns vintage: the 'encryption' that's hidden more spoilers than your startup's pivot plans ever will

The ROT13 cipher has been a longstanding method for hiding spoilers on the internet since its inception. Developed in the early days of online communication, ROT13 is a simple substitution cipher that replaces each letter with the 13th letter after it in the alphabet. This technique has been used by online communities, including newsgroups and forums, to conceal spoilers for movies, books, and other media. The cipher is not intended for secure communication, but rather as a way to avoid revealing sensitive information to those who do not want to see it. With the rise of online discussions, ROT13 has become an essential tool for avoiding spoilers, particularly in the 1980s and 1990s when the internet was still in its early stages. Companies like Netscape and Internet Explorer supported ROT13 in their early browser versions, allowing users to easily encode and decode text. As the internet continues to evolve, ROT13 remains a widely recognized and used method for hiding spoilers.
