In the case of the Spezzanos, they frequently pose as artificial family authority figures, providing an instant home for emotionally vulnerable (and financially affluent) people. In Asia, Mr. Spezzano is frequently called "Uncle Chuck." Lency is also known as "Mom" to several Psychology of Vision followers. This is hardly consistent with practices by real professionals in the field, but totally consistent with cult behavior.
In one Youtube, we see Lency calling POV trainer Melissa Meyer "my daughter," demonstrating how the Spezzanos promote this sort of relationship where their followers are kept in perpetual child status.
Remember, neither one of the Spezzanos are psychologists or licensed or qualified to be offering any sort of healing services. Their clients should be considered victims rather than customers.
