Two that I know of -
There was an elder a lot looked up to. He was a great person and had a storybook family; loving wife and 2 kids. As the story goes, his wife met an apostate and woke up pretty quick. The story continues that the elder and his wife got divorced because he couldn't take her constant apostate attacks. Within a couple of months following all that he was "free to remarry" and did.
The second is not so cut and dry. My father was disfellowshipped. He had been sharing things he had learned in studying the Bible. Eventually he was called to a judicial meeting and asked if he believed he was part of the Faith & Discreet Slave. He answer in the positive (keep in mind this was about 30 years ago) as he professed to be one of the Annointed. He was never told why he was disfellowshipped, but a friend of mine was at a get together where one or more of the elders on that judicial committee was present. My friend overheard one of the elders state that they just had to disfellowship someone for apostasy. The funny thing was the congregation presiding overseer looked into it about a year later and told those elders they needed to reinstate my father.
