I originally posted this as an answer (10k only) to the feature-request Prevent posts with links to jsfiddle and no code. Ben is uǝq backwards suggested to post this as a dedicated bug report because the original request has been completed already. That makes sense, so here we go:
I just discovered that some users already find their way around posting jsfiddle links without also adding some inline code into a question:
So I suggest a code block containing jsfiddle links should not be counted as code block when ensuring that there's some inline code besides a jsfiddle link...
EDIT: I changed the meta-tag to discussion to encourage some more opinions on this topic, because this is not a bug, but a feature-request, if at all.
