I just failed this Late Answers auditthis Late Answers audit, where the answer by itself appears a reasonable self-answer, but it was apparently downvoted because, commenters alleged, it was a duplicate of an existing answer; there was apparently no problem with the content itself.
There's no way to identify issues like these when comments are hidden and the audit system lies about the answer score; I'm not sure about all of the tradeoffs, but showing comments for LA reviews seems superficially reasonable.
