Well, a fella that made a site with a cc-by github repo.

So I used the vast majority of his site to make mine.

In the last few months he's removed the CC licence and added this to his readme:

"open as a learning resource, but this is not a template. You're free to re-use parts of this codebase in your own site, with attribution. Just don't copy the entire thing, replace the content and publish it. You know - be nice about it."

Looks like I've got some work to do on my website :/

Wish people would use the right licence in the first place. Rather than pick the one that makes them feel altruistic and then call people not nice for making use of the licence.
Fork it from the commit before. Tell the author that you've done that as a "learning resource" for his benefit.
