The Oxford English Dictionary lists a > total of 5 meanings of the word "defraud", one of which is: > > 1. c. absol. To act with or employ fraud. Your dic. is bigger than my dic. (mine's only 1500 pages :-) and so I'll have to admit to being wrong about "defraud" not having a recognized meaning without the aspect of theft or injury, etc. In response to your response, I will note that the meaning of "fraud" is more-or-less irrelevant to my dic.'s definition; the point is that it involved a "taking" or "deprivation", not just a "fraud", which ever sense anyone wishes to assume for "fraud", and not a simple identity confusion. I believed that many people, including you, thought otherwise and I was trying (wrongly, I must now admit) to disabuse you of the notion so that you don't accuse people of using the legal form of fraud and having it being interpreted as the illegal form of fraud, thus damaging their reputation and making you subject to libel laws (even in AU, no doubt). Now knowing the ambiguity of the term, not just in many people's minds, but in the OED, my point is even stronger. Of course, you free to ignore it; few are sued for their libel. Furthermore, after the intervening discussion, I'll even have to agree that some lawyers could find that any form if identity confusion or mail-filter penetration (even not for the purposes of spam or theft or damage) actually is damaging or costly and so the accusation would not be libelous in any case. You're free to call me a crook for allowing someone's mail software to form my Message ID. And I've been obstinate about changing my local host's name to match my ISP account name for years I don't see it changing any time soon and I won't be in any hurry trying to figure out how to kludge up my Message ID to not not [a poor attempt at making a point there] penetrate someone's unique idea of a mail filter rule. Anyway, I'm always glad to learn about words. Thanks for the info. I almost forget: Do you know what "c." or "absol." means in your OED quote above? (My dic. was inadequate again.)
