Another controversy over Facebook regarding the Arab-Israeli conflict concerns Facebook groups which , against Facebook 's terms of use , promote hatred and violence . According to former Israeli Prime Minister Shimon Peres , Facebook has been used to promote anti-Semitism and anti-Zionism . A proliferation of Facebook groups praising the perpetrator of the Mercaz HaRav massacre in 2008 prompted the creation of the Facebook group " FACEBOOK : Why do you support Anti-Semitism and Islamic Terrorism " , which claimed to have succeeded in deleting over 100 pro-Palestinian Facebook groups with violent content , by reporting the groups to Facebook . The group , which since evolved into the Jewish Internet Defense Force , took over the Facebook group " Israel is not a country ! Delist it from Facebook as a country " when , according to the JIDF , Facebook stopped removing such groups . After taking over the group , the JIDF began to remove its more than 48,000 members and replaced the group 's graphic with a picture of an IAF jet with the flag of Israel in the background . This sparked controversy
