Some Facebook users were surprised Wednesday night when hundreds of personal messages not meant for their eyes landed in their inboxes. A WSJ.com editor happened to be the recipient of some unintentional messages: “I am sorry for letting my jealousy and worry get the best of me,” one read. The editor also received a copy of one couple's entire explicit chat conversation. Facebook recently updated its privacy settings to make them more user-friendly, but the recent snafu will leave many questioning the site's security. “Our engineers diagnosed the problem moments after it began and are working to get everything back in its rightful place," a Facebook spokesperson said. "While they fix the issue, affected users will not be able to access the site.” Although Facebook deleted all of the relevant messages during this time, copies will remain in users' third-party email accounts.
