[...] I think the statements about "getting around the limit" in the above posting shows that the author seems to be confusing two "problems" [I put "problems" in quotes as I am not willing to admit that either is sufficiently obnoxious so as to require a software-based correction]: 1) Certain large individual articles may harm particular systems by filling up disk partitions allocated to news or causing transport-level (e.g., UUCP) problems; and 2) Certain individual posters are thought to abuse the network by posting too many bytes (in the aggregate) in too short a period. If #1 is seen to be the problem, then there is nothing wrong with "getting around the limit" by splitting large encoded articles into parts. This is the accepted practice in groups that contain uuencoded binaries or image files. All that a site needs to do is reject incoming postings that are longer than a certain site-specified threshold. I would support a modification to the news transport software that implemented this. There is no need to send complaining mail to anyone or their site administrator about large postings; just drop them if your site can't handle them. It's your site's problem, not the network, so I suggest fixing the problem there. If #2 is seen to be the problem, we will need some very sophisticated software to sum up and drop/complain about agreegate postings by an individual. I personally don't see the need. As far as our site is concerned, large postings do not (yet) cause a problem. We got the massive Monty Python article and it got posted like anything else and expired when appropriate like anything else. (We receive news via NNTP which is able to handle arbitrarily large articles, and have a decent-sized news partition.) Sites which are affected by large articles should either install filters to protect themselves, or drop those groups in which large articles often appear, i.e., the binary and image groups. -- Michael C.
