According to Ha’aretz, the majority of the Tweets came from Arab countries or Iranian or Palestinian users.
Twitter has fallen victim to false stories and users impersonating celebrities a number of times.
Last week, JC columnist Melanie Phillips blogged that she had not joined the site, despite a fake Melanie Phillips amassing 800 followers in three days.
There is, also, a presumably fake Ariel Sharon account on Twitter, with 254 followers, although its author has not been active for more than a month.
