Defensio provides useful statistics to the blogger. A typical response would look like:
1 --- 2 defensio-result: 3 message: "" 4 status: success 5 signature: awnc057e1a132p1jj3t4x 6 spaminess: 0.7 7 api-version: "1.1" 8 spam: true
Notice how Defensio returned the spaminess and a signature ? The signature can be used to retrain Defensio. When a false positive or negative comes through, the Defensio API simply accepts a series of signatures, and will retrain itself. Since the signature is a short-hand for the whole comment, all of the data is available for retraining: IP, author email, author name, comment’s body, etc.
It is not obvious from the screenshot above (as I mostly get spammy comments), but there are actually many shades of orange to highlight the spaminess of comments. Lighter shades are non-spammy, and darker ones, spammier.
