I doubt that line ("ourhardworkbythesewordsguardedpleasedontsteal") is creative enough to meet the threshold of originality required for something to be protected by copyright.
Even if it actually were copyrightable/trademarked it wouldn't be a valid legal strategy to prevent fair-use:

I would not be surprised if a DMCA takedown will be filed against this repository soon.
