Seeking subjects to interview, regarding their workplace experiences with uber-controllers, bullies

I am writing an article on uber controllers and bullies in the workplace, and would like suggestions for where I might go online, to invite people to interview with me regarding their experiences with such.

I just had to leave an excellent job with a world class org (non-profit research org in Seattle) due to the ultra-controlling behavior of my former manager. Interviewing and writing is something I love, so thought I would collect stories of others experiences with this kind of personality disorder and write an article about it. I am former therapist, current business analyst and have interviewed thousands of people over the years, for a variety of purposes.

Controllers, Bullies, and Meanies, oh my

I have first-hand experience with this managerial style in my past. It's healthy to move beyond such things, but there's validity in documenting it. Please feel free to contact me.

Control freaks gain power too frequently

I've experienced this three times in my career and would consent to an interview, as long as I can be vague enough to protect my identity. Isn't that the pits? I suffered through these hideous workplace relationships, and then fear to go completely public.
