Can I do this with FuzzyOCR?

[Robert Nicholson]

So currently FuzzyOCR is not getting hit on this drug spam however  
I'd like to force the recognition of this image as spam for future by  
generating a hash and adding an entry into the hash database that  
this email is spam....

How can I do that?
I want to manually add an entry to the hashing database that this  
email is spam.
