I would probably not mention the corresponence on the FB account. It gives you an idea of what is being said about you behind your back (or in this case in front of your back).
I would change halls, as it appears that the elders are likely to be punitive toward you. The elders at another hall could be your advocate in case they stonewall your reinstatement.
I had a situation like that with my ex-wife. She would keep stirring the pot with the elders from her hall. I moved back to my home congregation, and those elders requested that my original committee should reinstate me. They had stipulations on it (instigated by my ex). After 4 attempts and getting the CO involved I finally got reinstated. Sometimes you need to have a fresh perspective when you have someone badmouthing you.
That was a long time ago, I am gladly out now. Good luck!
