And, it's up to the user and the user's MUA to add/update these headers and some don't so you can't rely on them to determine whether or not a message is a reply to any other particular message. Also, users often hijack threads by starting a new, unrelated thread as a reply to a message in an existing thread. In short, relying on something which is basically under control of the user to determine whether or not the user's post will be throttled will just encourage users to find ways around it. Case in point. I once tried to determine how much of a post to a discussion list was original material and how much was quoted from prior posts. The goal was to stop people from quoting entire messages when they were only replying to one small point or where the quote might even be completely unnecessary to establish the context of the reply. I tried to determine how much was quoted and how much was new and had an algorithm for determining whether there was too much quoting and held or rejected the post. A few people almost immediately started gaming the system by adding a bunch of "new" nonsense to there posts or altering their posts so quoted material wouldn't be recognized as such. The irony is that rather than simply deleting irrelevant quoted material, they went to extra trouble to ensure it would be accepted. -- Mark Sapiro <m...@msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
