It also means you get nothing for your hard work and anyone can claim your work as their own. They won't be successful if they also don't understand it, but it still muddies the waters. If you try to come forward to put your name on it, you'll find resistance and be forced to prove who you are, but that's going to require records from 4chan and maybe your ISP, which may no longer exist. I've forgotten if 4chan post hashes (to identify a unique, anonymous user) can be reasonably brute-forced to find a collision.
The standard solution to this is to include an encrypted message that says something like "The author of this document is My Name", and then publish the decryption key when you want to claim authorship.
