Have you ever been harassed on the Internet? If so, you're not alone. The three most visible organizations that deal with cyberstalking and similar Internet issues receive about 30,000 complaints a year, according to Jayne Hitchcock, the president of one of them. And this number is related to adult crimes, not those directed toward children, says Hitchcock, who founded W.H.O.A. (Working to Halt Online Abuse), at www.haltabuse.org, in response to her being stalked for more than three years. In 1996, Hitchcock, a professional writer, warned others publicly in a Usenet discussion group about a self-described literary agency that required fees for reading book manuscripts, a shady practice in the book publishing industry. Some legitimate professionals charge to read and edit book manuscripts, but agents typically earn their fees as a percentage of royalties after books get published.
