Newsgroups: news.admin.policy From: hoey@zogwarg.etl.army.mil (Dan Hoey) Date: 9 Feb 93 14:55:10 GMT Subject: Re: Anonymous postings to non-personals newsgroups Having seen several attempts by students in introductory computer science courses to get their homework done by the readers of comp.theory, I was somewhat dismayed to see the anonymous posting service used for the purpose. So far there has been only one such use, though that seems to be the only use of the service on comp.theory so far. While there has never been any real security against anonymous or forged postings on Usenet, the process has until now been sufficiently inconvenient, error-prone, and undocumented to limit its use by persons who have not learned the culture of the net. On the other hand, a recent use of the anonymous posting service on sci.math seemed seemed to be a student asking help on a homework problem. It has now been attributed to a teacher, asking for an explanation of a dubious answer in his teaching guide. He says his news posting is broken, so he is using the anonymous service as a mail-to-news gateway. Gateways from mail to news have provided a fairly easy method of forgery and anonymity in the past, though they are somewhat less prone to abuse for several reasons. First, their use does not provide anonymity by default, nor does it promise anonymity. Such gateways may in fact keep enough records to trace back to the poster in most cases. Second, the gateways do not provide a covert address for private, anonymous communication with the poster. Thus the cheating student must either provide a private address or make do with that information that gets posted in the newsgroup. The inherently greater risk of detection would be likely to reduce such abuse. For these reasons, I think such gateways are much less harmful than the anonymous posting service. It is unfortunate that no well-known mail-to-news gateways seem to exist outside of the anonymous posting service. Dan Hoey Hoey@AIC.NRL.Navy.Mil
