The Sjin Bet security agency has cautioned the Israelis from replying against the unknown messages or divulging sensitive information through internet. The agency mentions numerous incidents in which violent groups tried to recruit Israelis through Facebook and other networking sites.
"Terror organizations are using these sites to tempt Israelis to meet up in person in order to either abduct them, kill them or recruit them as spies," says the security agency
In recent years, militants have turned to the Internet to battle Israel. Hamas militants in the Gaza Strip have been using Google Earth for better precision when firing rockets at southern Israeli cities.
Facebook does prohibit content that is hateful or threatening, and users are barred from doing "anything unlawful, misleading, malicious, or discriminatory." But, the networking site does not hand-screen all the content on the site before it is posted.
