Spam Comment Moderation, Like Spam Blog Classification, Is Fuzzy

For years, we've been seeing numerous complaints in Blogger Help Forum: Something Is Broken about unrighteous spam classification of blogs.

My blog is not spam! How could anybody think that my blog is spam??

In some cases, these complaints will be posted by spammers, seeking to make trouble in the forums - in other cases, though, they will be righteous, and deserving. In the latter scenario, and following the well known (and not completely popular) 4 step spam review process, some folks see the welcome message.

Your blog was restored. Thanks for your patience.

One of the reasons for falsely accused blogs relates to the fuzzy spam blog classification process - which is necessitated by ever changing spam blog design. Like spam blog classification, spam comment moderation is fuzzy.

With fuzzy spam comment moderation, as with fuzzy spam blog classification, there will always be some spam comments that sit in the "Awaiting Moderation" queue (false negative detection), and other non spam comments that are immediately directed to the "Spam" queue (false positive detection). And like fuzzy spam blog classification, if you reduce false negative detections, you're going to increase false positive detections.
