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.
The blog post and the README both seem to encourage use of the project. And a license that prevents all use including personal is very rare and not exactly in the spirit of GitHub. So I’m curious why both the blog and your README don’t mention explicitly that you don’t want allow use or explain why. Would it be worth putting something at the top of the README?
Non-free licensed code has been on GitHub for quite some time. It's not only about free software and you should not assume so, as in all software.
Edit: changed FOSS to "free"
