NASA logged over 30 million hits per day. For many users, however, the pictures that appeared on their screen were not rocks from Mars but naked women advertising video-stripper services. Over a million people a day were subjected to this. Because of their relative anonymity, newsgroups contain much of the Internet's worst material. Subjects ranging from pedophilia to bestiality are categorized for easy reference.
Pornography can be rampant even in newsgroups devoted to innocuous subjects.
For this report, I used the example of a child looking for information about Disneyland. The results would have been much worse if I had used the example of a child looking for pictures of other children. Please note that Disney has no control over this material and is in no way responsible for this content. A child opening this message would be confronted with a picture of a naked Pocahontas. These email messages often have misleading subject headers, so the child is exposed to the smut without any warning.
