That looks nice. It is good to have another option than akismet for that, especially an open source one we could host ourself if necessary. And do I see that right that no API key is necessary?<p>How do you protect yourself against spammers falsely classifying their comments as ham?<p>I&#x27;m not sure I want to integrate that for ursprung. So far, the local methods were enough (and the bayes filter easy to provide via a gem), if that changes for me or others I will reconsider. But serendipity (<a href="http:&#x2F;&#x2F;www.s9y.org&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.s9y.org&#x2F;</a>) should get a plugin for that. that is certainly used in places where more options would help. I&#x27;ll look into it.
