Facebook bug may have exposed moderators to extremists

SAN FRANCISCO (AP) - Facebook has acknowledged a security hole in its software may have exposed the identities of its online monitors to suspected terrorist groups and others whose pages were removed for inappropriate content.

A Guardian report said more than 1,000 people, which Facebook calls moderators, were affected. Facebook said it fixed the error, which occurred last year, and it has no evidence those affected received any threats.

The Guardian said six people likely had their profiles viewed by suspected terrorists. It spoke to one of these people, whom it did not name, who went into hiding following the incident. This person was worried sympathizers of the Islamic State group may have viewed his profile.

Facebook said it didn't find any profiles were viewed by suspected IS members.
