How many local JWs do you still have contact with? If you really don't care about the cult anymore, disfellowship them! Send them notice that you've disfellowshipped them in absentia for gossip and slander.
If you still have contact with JWs, tell them individually absolutely everything that is going on. The elders get power from "confidentiality" and can become drunk with the power that they can do whatever the hell they want and you can do nothing because it's all secret. From my own experience back when I was removed as an elder, I leaked nearly every word of the "secret meeting" to my parents and the congregation busybodies, so that the whole sham was an embarrassment to the BoE. I even reported everything that happened to WORLDLY PEOPLE that know JWs and were horrified by the injustice. After that, the elders were all very careful about what they said because they realized I could report it back publicly... and that's exactly what I did. They lost their power. They could no longer secretly threaten, "we have been informed that you did such-and-such", because I would ask, "by whom?", and if they didn't answer, I would speak to everyone I knew about "who is making this accusation without asking me about it first?" I think the elders were relieved when I moved away.
So far, I think that me and my siblings that have faded haven't been pursued like this for a couple of reasons. Two of us have moved far enough away to a big city that nobody could report "wrongdoing". But the faded family that is still local is left alone because the elders can't do the typical "secret intimidation" like described in the OP. For the faders that still live in their territory, they are pretty much left alone because they know if they rock the boat, it's the local JWs that will get seasick when every detail of any such "judical proceedings" spreads like wildfire through the congregation and community.
