[extropy-chat] spam & spelling?

I'm sure this has occurred to developers working on spam filters, and 
perhaps it has even been implemented, but anyway:

Why not judge email messages by spelling errors, and if they have too 
many then they get marked as spam? This would seem to get around the 
current problem of spammers coming up with all kinds of misspellings to 
get around current spam filters. And most mail clients have a 
user-extendable dictionary built in already for spell checking that 
could be used.

Now to catch a high percentage of spam you might have to set this kind 
of filter to judge pretty harshly, and it might tend to catch legitimate 
emails. So it will have to be used as only part of a larger spam filter 
algorithm, but I do think it would help.

Anyone know of any filters that use this technique?
