A Facebook notification on Gary Bernhardt's phone woke him up one night last November with incredible news: a message from Mark Zuckerberg himself, saying that he had won $750,000 in the Facebook lottery.

"I got all excited. Wouldn't you?" said Mr. Bernhardt, 67, a retired forklift driver and Army veteran in Ham Lake, Minn. He stayed up until dawn trading messages with the person on the other end. To obtain his winnings, he was told, he first needed to send $200 in iTunes gift cards.
