Italian politicians are to vote on legislation to force internet providers to block Facebook pages encouraging criminal activity.
The measure would apply to all websites and require content to be blocked within 24 hours, according to the Guardian newspaper.
The measure is contained in an amendment to a public security bill approved by the Italian senate. It will now go to the vote in the lower house.
The amendment was initiated by a row over Facebook pages set up to honour members of the Italian mafia who have been linked to hundreds of murders.
The move follows an attempt by the Italian authorities to clamp down on websites providing user content by charging Google employees for failing to protect personal data.
The charges follow a two-year investigation by Italian authorities into a video posted to Google's Italian website. The video depicts four teenagers mocking a disabled classmate.
Google's global privacy counsel Peter Fleischer, chief legal officer David Drummond, former CFO George Reyes, and a former London-based Google Video executive face up to 36 months in prison if found guilty.
The trial, scheduled to resume in Milan tomorrow, will examine the degree to which Google is responsible for content supplied by users of its video service.
