Yeonsangun banned Hangul because people were writing mean things about him lol

When anonymous posters started putting up signs criticizing him in Hangul (because commoners couldn't write in Chinese characters), Yeonsangun's response was to literally ban the Korean alphabet. He shut down the Office of Eonmun and made it illegal to use Hangul. Imagine being so thin-skinned that you try to cancel an entire writing system. This is giving "blocking everyone who quote-tweets you" energy. He also turned the national university into his personal party venue. Speedran getting deposed in 1506.
