I have just found the title of a science fiction
story written by Robert Silverberg that is about
organized shunning in a society.
A brief description from the internet of this
story follows:
------------------------------
To See the Invisible Man (1962)
by Robert Silverberg
As punishment for his antisocial behavior, a man is sentenced to a year of invisibilty. People can still see him, but they are required by law to have nothing to do with him--no conversation, no contact, nothing. There is a fun side to being invisible--he goes to movies for free, walks into women's locker rooms, and so on, but doctors are not exempt from the law, so when he gets sick, no one will treat him. An interesting concept, this modern version of shunning, though it's hard to see how doctors could reconcile it with their Hippocratic Oath.

Sounds like WT shunning policy taken to the extreme!
