This same problem just broke my site as well.
I’m having this issue too. Has anybody else experienced this?
Ah ha! I’ve figured it out… Just writing out the problem above helped me realize. The theme is using a javascript function to replace a font… By disabling it, I’ve fixed the issue. 🙂 YOu can find the function being executed in the the top of the header file if you are curious.
But i doubt all the posts are coming from the same spam-bot. Why would every single spam-bot go right to that post? It’s not particularly recent or popular…
