Sorry to be blunt, but for a contractor to publicise their internal affairs with one of their named clients is extremely unprofessional behaviour, and I am wondering if they can be sued for damages. Even if they had been an employee this would have been questionable at best. If this website is for self-healing purposes, then that's fine, but should not and does not need to name the parties involved. (Do I see it clearly that the author even remains anonymous?)
