This is a very common problem on Usenet. It seems most people add a sentence or two to a post already hundreds of lines long. Very frustrating to us with slow modems and connections since we have to wait for all that garbage to page through, especially when the added line is merely "I agree". Google as a news reader blanks old stuff out unless you ask to see it, this is a big help.
