When people reuse content in other websites/blogs/etc, they have to copy the article text and link to Italian Wikipedia where you can check the entire history and authors. That is how attribution is given. It is explained here http://en.wikipedia.org/wiki/Wikipedia:Reusing_Wikipedia_content
Now, most of all the attributions to Italian Wikipedia contents on the Internet are broken.
Only reusers would be violating the license and I don't think that disattending a point of the license for 43 hours could be considered a serious violation. In any case, yes, reusers are taking their risks when they follow the easiest way for attribution.
