I just heard of two:
As we were two "brothers" df'd for "apostasy" at the same time the rumour went that we had been df'd for homosexuality (heard this one from a former "bible study" I visited a few weeks later in a previous congregation, hundreds of miles away from the one I was df'd in).
As I had been a translator in Bethel another rumour went that I had been sneaking apostasy into the French Watchtower (although I was df'd months after leaving Bethel; that one I heard from my father, years later).
But I guess there are a few other stories I won't never hear of.
