Stories of cult behavior are a warning bell to wealthy families of their vulnerability to people of all kinds with ulterior and sometimes nefarious motives.

Social media and techniques like social engineering can readily be used by protagonists to worm their way in. When it comes to trust, families should observe a healthy (but not obsessive) measure of vigilance. by David Werdiger
