The biggest error I see here is that people are trying to limit language versions of Wikipedia so that they comply with the laws of the country where the language is primarily spoken. But that's fruitless. The Italian Wikipedia (hosted in Florida) isn't under Italian law just because it's in Italian. Nor are Italian citizens liable for something on the Italian Wikipedia just because the page is in Italian.
I politely disagree. When the person doing something has the Italian nationality, and the person commits the act from italian territory, and the claiment is italian, an italian judge might well decide to consider the claim, despite the servers being in the us.
