Ask HN: Is there a spam filtering web service?
After reading Resig's post about Google Groups, I was wondering if there exists a web service that specializes in filtering out spam.
I would imagine I could create a new filter, send training data to a filter, and send data to a filter and have it return the likelihood of it being spam.
Anybody have first hand experience using a web service like this? If so, has it met your expectations? Well, Google's own Postini does spam-filtering. I could imagine a setup where you have people send mail to an alias on your domain, route it into Postini, and then into Google Groups. The big problem would be getting users _not_ to send directly to Google Groups. And I'm not sure you'd even be able to tell them (direct vs. filtered) apart in Google Groups... Can someone outline for me the pros/cons of a mailing list vs. a forum? Except for the registering-over-and-over-again issue, it seems like forums would be preferable generally... (Especially given that most will send you emails with new posts if you ask it to.) Akismet does just this for blog posts. Defensio? Ah, thanks. Any first hand experience using it? Yup, I interface with it using this plugin: http://github.com/mattapayne/rdefensio I've done the integration work, but haven't put it into production, so I can't speak to how well the actual service works.
