I'm having marvelous luck with FuzzyOCR - but the spammers are learning too.
When I first started using it just a couple of months ago, it really
whacked the image-based spam. You could see why when "gocr file.gif"
returned nice text that was easy to match against.
However, now is a different matter. I just got a "lose weight" spam 10
minutes ago that gocr returns as:
lI__c_tc)r _rc_hc_rihc_Ll _cnLl .h1c_Llic_;cll_ _u__c_c __ihc LI
l c htc)hlc_rc)c_c_ B llr_ll l hc r_cp_

That tells me to go to "www.realhgh" dot org , but their GIF processing
munged it enough to slip by gocr
Not much FuzzyOCR can do with that :-(
