Looking through this thread, your contribution to it seems to be telling her that her husband committed a serious crime and that he deserves to be punished. How is that constructive criticism? She wasn't asking to be told she was getting what she deserved, she was asking about the possibility of appealing.
She was absolutely right to point out that there are precedents of people committing misrepresentation who had their exclusion/cancellations reversed on appeal. Whether that's normal or not, or whether it happened more in the past than today, is a question for a lawyer. Perhaps she got a little more upset than is called for, but in general that's acceptable for people who are worried about serious questions.
