The Imminent Rise of Social Cloud Computing - Technology Review: " University of Minnesota in Minneapolis suggest a fix. They say one solution is to distribute tasks only to people you trust, as defined by your social network.
Their idea is to ask members of a social network to make their computers available for processing tasks when the computers are not otherwise being used, rather in the manner of distributed computing programs such as SETI@Home. Then whenever a user outsources a task, the burden is passed to their friends; in other words, to nodes directly connected to them on their social network."
