It appears that a person working for the Occupy movement did a really crappy thing
For those who want a summary/more information. Lupe Fiasco is a celebrity that is active with the Occupy Wall Street movement and had been to some of the protests and RT's protesters and news dealing with it. Apparently, someone working for the Occupy protests got his information and spread it over the internet.
Looks as if someone found some information on this guy: http://www.zimoz.co.uk/news/internet/double-agent-infiltrates-anonymous-hackers/
Obviously hid his number. I'm assuming he tweeted the person who posted his number in revenge and to bring attention to this twit but his number is out there =/ So wrong what that person did
