If by redacted, you mean they were removed, they were violations of the rules. You can appeal violations, but that rarely works. If you want to know the reason for the violation, post "Why was this question (answer) a violation?" and add the original e-mail you got and/or any details you remember so the users can see the exact context. The experienced users here will explain it to you. Many times the violation is not in the question but in the added details and updates.
