Distributed Blacklists for Spam Prevention

Andrew Newton introduces the idea of Distributed Blacklists for the Blogosphere, a method for creating spam blacklists which leverage a peer to peer web-of-trust as opposed to a centrally managed list, hopefully providing greater accuracy and understood accountability.

Complete details on a possible technical implementation of the concept are here.

This is a great concept for ‘power bloggers’ and hosted weblogging services; by sharing with each other what they know about blog spam it might be possible to more effectively protect blogs from spammers.

We’ll still need some forms of proactive methods for protecting your blog against previously unknown spammers, as I wrote about here. But by combining your own techniques for protecting against spam whatever they might be with blacklists of banned IP addresses created by individuals and groups you trust will certainly prove more effective than either technique used by itself.
