I think you posted on the "other" site, and I responded there. My suspicion is that CACH forges these allegedly "OC" (BofA) affidavits. Every example I have seen in various online forums has an affiant with a profile on LinkedIn. I suspect they are getting names off the internet.
The notaries are legit, according to the NC secretary of state. But there are ways to get this info and forge this too. The signatures are all illegible, scribbles that anyone could make.
Maybe we could get some AG interested in taking them down?
As for the OP's situation, the arbitration strategy should work very well for you.
