FUZZY_OCR find not existent words on images

[Rejaine Monteiro]

I'm using FuzzyOcr plugin, version 2.3b and have some problems  with 
Fuzzy-OCR false/positives:


12 FUZZY_OCR              BODY: Mail contains an image with common spam 
text inside
                           Words found:
                           "news" in 5 lines
                           "money" in 1 lines
                           "million" in 1 lines
                           "trade" in 1 lines
                           "levitra" in 1 lines
                           "product" in 1 lines
                           (10 word occurrences found)

So, message was targed as spam..

But the image on this message have NOT any words above (have only 
brazilian portuguese words)

Any tip?
