The Church of Scientology is a famously vindictive institution, prepared to use litigation and harassment to suppress critics. And nobody gets kid-glove treatment, not even relatives of the sect's high priest, David Miscavige.

The dreadful price: "At least eight friends have removed themselves from my MySpace page."
