Facebook at Immigration
"A trusted colleague - who is married to an Iranian-American and would thus prefer to stay anonymous - has told me of a very disturbing episode that happened to her friend, another Iranian-American, as she was flying to Iran last week. On passing through the immigration control at the airport in Tehran, she was asked by the officers if she has a Facebook account. When she said "no", the officers pulled up a laptop and searched for her name on Facebook. They found her account and noted down the names of her Facebook friends."
