Increase in Image Spam

[Andy Jezierski]

I've been seeing a pretty big increase in image spam over the last month 
or so. I remember using FuzzyOCR years ago when image spam was a much 
bigger problem.

Since FuzzyOCR hasn't been maintained in several years, is there an 
alternative that would work?  Or is there another way to try and catch 
them?

They don't really hit on any rules....

X-Spam-Status: No, score=3.5 required=5.0 tests=BAYES_99,HTML_MESSAGE,
        SPF_HELO_PASS,SPF_PASS autolearn=no autolearn_force=no 
version=3.4.0-rc5 

Thanks
