As anyone can see from the DNJ weblogs home page or the ASP.NET weblogs home page, comment spam is a problem. Jay we understand how you feel! Of course, feeling that I am obviously smarter (ha ha) than the hundreds of super-intelligent people working on this problem, I’d like to offer my two suggestions.

For a short-term fix, disable any comment with more than 1 link. These spammers are using 1 comment to boost some 20 or 30 of their web sites. If we make that only 1 for 1, it will massively cut their productivity for a while. This would give us enough time to implement the long-term fix.

Long-term, why not use Bayesian filtering, similar to SpamBayes? It’s pretty much the same thing, comment spam or email spam, it’s all SPAM! And the benefit with Bayesian filtering would be that you could scale the effort in training the filter across all of the bloggers on a site! I have a feeling that the type of comments left in technical weblogs is vastly different than links to pharmacy and gambling sites.
