The source text should be corrected. The official name of the license is CC BY-SA 3.0 (only one dash) per.

Taking one step back. Is it possible to ferret out all of the messages (source at least) including the literal "CC-BY" since theses would all be wrong as well (I see that a lot of them have been replaced but not all).
