It's an interesting thought. If you are an ex JW, presumably dfed, and you see a current JW in good standing engaging in behaviour that would concern their elders, would you pass on that information to interested parties? Do accusations from exes and other outsiders carry any weight? Would they even be listened to?
I personally doubt that any of the exes here care enough to do such a thing. After all, you left for many reasons, including the crappy way judicial committees treated people. Why would you stir anything up?
It's just an interesting thought I had based on the 1987 WT article about Mary using privileged information against a fellow congregant. Does testimony from a non JW third party count as evidence to a JC? Given that they don't even give credence to a police investigation as evidence, I'm guessing "No".
Thoughts?
