I'm sorry to hear of your troubles and the outcome, but surely you understand the need for people who work with children in any capacity to be vetted and registered? Please do not take that as any kind of insult or slur, as I know your intentions are nothing but honorable, but the fact remains that there are predators in the world, and children must be protected from them as much as possible. Best of luck with any appeal you may decide to launch, and of course, best of luck with your condition. Just remember that they are not having a go at you on a personal level, but a bureacratic one, which, as petty as it may seem at times, exists to protect children.
