A new web trolling campaign to spread the rumor that Afghan President Hamid Karzai has converted to Christianity was sweeping the internet on Thursday, calling on people to "exploit Islam's hatred of all things Christian." Web trolling involves posting inflammatory statements online to provoke reactions.

Running with the title "Operation: Desert Troll," the call to action urged readers to use tools such as blogs, twitter, reddit to spread the message. Internet users were also asked to search the term "Hamid Karzai converts to Christianity" to further circulate the rumor.
