The French Union of Jewish students is preparing to take on one of the giants of the internet – Twitter – and they expect to win.

They want the micro-blogging site to reveal the names of people who post anti-Semitic tweets so they can be prosecuted for hate crimes.

It began in October with one of two people posting under the hashtag ‘a good Jew’, but it grew into a wave of hateful messages becoming the third most popular subject on Twitter in France.
