I suppose that there are people who just have to argue and/or disagree, but this, from the FAQ, seems perfectly clear to me:

"The Mudcat Cafe reserves the right to edit, move, combine, rename, or delete all threads and messages posted in the Forum. We will try our best to edit sparingly, but there are times when we may have to take some action to keep the peace, or to protect the interests of our community. Editorial decisions are made by Max, Jeff/Pene Azul, and Joe Offer, or under their direction. We follow principles and common sense, and see no need to have everything spelled out in some sort of pseudo-legal code. We don't allow hate, racism, stalking or other intimidation, or personal threats or attacks. We don't cater to chain letters or non-music advertising, and we expect people to use moderation when they advertise music-related things. We allow just about all sorts of discussion, but we draw the line when it's clear that an individual is flooding Mudcat with information - things like multiple "copycat" or interrelated threads, lengthy copy-paste messages of non-music articles from publications and Internet sources (one screen full of text is the limit - and remember that we encourage you to post the entire text of music-related information). If you regularly start more than one thread a day, you are quite probably starting too many. Please try to post to existing threads as much as possible, rather than splitting topics into a number of threads. I suppose there are a few other things we take action against, but I think this is a pretty good summary.

When we encounter individuals who cause us continual problems, we may take action to temporarily or permanently bar them from posting at all, but this rarely happens. Most of these are people who post just because they like to cause trouble. They may become very self-righteous in defending their right to "free speech," but it's usually quite clear what they're up to. On the Internet, they're called "trolls." We deal with them as we see fit."
