The Jewish Internet Defense Force (JIDF) is an organization that uses social media to mobilize support for campaigns against websites and Facebook groups that promote or praise what it regards as Islamic terrorism or antisemitism. The group's website describes the JIDF as a "private, independent, non-violent protest organization representing a collective of activists".[3] The JIDF's work has been termed "hacktivism" by some media outlets.[4][5]
