               Nice to see, in the midst of all these scandals, Yahoo
               turning a healthy profit. But as other companies fiddle the
               figures, Yahoo's been busy instead with fiddling its own
               users' private correspondence. In a fantastically clumsy
               attempt to prevent cross-site scripting attacks, the free
               e-mail wing of the sprawling giant has long been replacing
               complete English words in the text of HTML mail sent to its
               users. Mention "mocha" in an HTML mail to a friend with a
               @yahoo.com account, and your choice in coffee will be
               silently switched to "espresso". Talk about "free
               expression", and your recipient will think you said "free
               statement". Here's the full list of swaperoos:

                                       - try not to mail it to your friends
    
               This fiddling has been going on now for over a year year
               (the ever vigilant RISKS digest noted it back in March
               2001). But because of Yahoo's underhand methods, very few
               people have spotted the turnabout - certainly far fewer than
               if Yahoo had done the sensible thing and, say, "**"'ed out
               the vowels in the word, or, God forbid, written a smarter
               parser. But the sneakier you are, the wider the damage
               spreads. The word "medieval" (since it contains the
               javascript command "eval") is converted in Yahoo mail to
               "medireview". Google now shows over 640 sites (and 1,150
               separate instances) of the word "medireview" being used as a
               synonym for medieval. University papers, bibliographies and
               book reviews, Indian newspaper columnists, and endless
               enthusiast sites drop it unseen into texts. People have
               begun to ask where it originally came from, and does it have
               a subtler meaning beyond "medieval"? Is Yahoo ever going to
               fix its filters? Or is it time we pushed to get the first
               regexp-obfuscated word into the Oxford English Dictionary?

                 - does anyone still at Yahoo even know how to turn it off?
