This is like the Salem Witch trials where a small number of people revel in their authority and use it to abuse others. They move from one victim to another and like a dog with a bone they will not give up until they get what they want.
The fact that the JC was unsuccessful does not mean that they won't keep harassing others in an attempt to get what they want.
You either have to accept that this is not a level playing field and fight the inevitable causing you stress and anguish or walk away show them how irrelevent they are to you and your life. These men live in a small world where they are able to bully other people and puff themselves up because the organisation enables them to do so. They have an inflated view of their own importance and are out of control like petty bullies in school. The biggest power you have is to demonstrate that their opinion is of no interest to you, that they have no power over you. If they try to talk to you or invite you to a JC say no I have better things to do. If they threaten then advise them that this is now a legal matter and they should under no circumstances contact you or continue to harrass you or they may be financially liable for distress caused.
I still remember the stunned silence when the elder called me to tell me the outcome of my JC (which I didn't attend) He said I need to speak to you. My response was "No you don't" and I put the phone down. It was great taking back the power and control.
