Who tracks such incidences ? The industry or their disciplinary board of peers in practice with them ??

Go to the 'Psychotherapy' board on this site and read the pages of boundary crossing that's publicly confessed on this internet site. If you're an individual who has ever been subdued and molested, it'll make your skin crawl.

A good read is the post between me and Junerain this morning at the 'Other Mental Health Discussions' board, found under Children of clinical behavioral studies.
Take the link to Ken Pope's study.
