The brief behind this video

Since 2011, one Reddit account has been posting messages nobody can read. No title. No explanation. Just walls of code — hundreds of characters of pure hexadecimal, posted at strange hours, sometimes several times a day. The account is called A858. And for over a decade, it has said nothing else. A community of thousands formed just to crack it. Programmers ran every decryption method known. Statisticians analyzed posting patterns. They found the messages weren't random — the data had structure.
