An older elder in our cong had a term he used for this when it happened to him: 'phantom accusers'.
And if there's more than one, they get to misuse the ol' 2witness rule against you. This happened to me too and was instrumental in waking me up. It was a sucker punch.
I was listening to a McNeill/Lehrer interview of one of Pres. Reagan's military strategists (can't remember the name right now). He wrote a book after the Berlin Wall came down something about the "Evil Empire". He made a comment about what he thought made Communist Russia an evil empire. When I heard this, I never forgot it, because it described exactly the way the borg works too and one of the reasons I think it's evil.
He said: "There was no security on a personal level against arbitrary attacks." (speaking of KGB)
I thought to myself: Bingo!
