Use the Defensio API to help manage spam on social web apps, such as blogs. Use a variety of functions, which return structured responses. This service is meant to ease the burden of spam across any type of social web app. The primary function you will use shows whether Defensio thinks a comment is spam or not, and also shows its spaminess level, which is how likely it is of being spam. Also, use the API to announce the existence of new articles to Defensio, report false positives, report false negatives, and get statistics. Defensio has OpenID functionality.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
