Hi, I had luck in stopping at least one organization from repeatedly sending me faxes by sending their fax back to them with a note on it saying that sending unsolicited faxes is illegal in Massachusetts and that if they didn't stop, I would report them. This was a legitimate organization, the publisher of a well-known public relations magazine. They stopped! Not sure this would work with the fly by night type of organization, however. Jeanne Yocum
