I love that all the discussion here is about the license I wrote and not about the actual project, which is a completely terrible idea and something I created as a lark. Why did I not spell this out in the blog post? For my own amusement. I also think it shows that licenses really don't matter all that much as some people think, they are not computer code.
They matter as long you're willing to enforce them, and have the time and money to do so.
In that case, you may be able to submit some form of take down request to GitHub against that project and other projects who are using your library.

edit: wow, one of the projects that depended on your library was arduino up to 2020. https://github.com/arduino/arduino-cli/commit/09b4e8804fbd61...
edit2: was also used by AWS up to last week when they removed it. https://github.com/awslabs/karpenter/commit/d84365e8c44178ea...
