Google announced yesterday that it is shutting down the consumer version of Google+. The news came alongside the reveal of an API vulnerability discovered earlier this year. The company will provide 10 months for users to download their content.
Defensio, the anti-spam service, offers an API that can be integrated into blogs and web sites to fight spam comments and other unwanted spam (details at our Defension API profile). The service appears to be run by a small team, and is similar in purpose to Akismet, the much larger spam filtering service from Automattic (which powers WordPress.com), who also offer an anti-spam API.
