Sites with pornographic content will be pulled. If root thinks it's porn, it's porn. See the next rule. The owner of madstop.org is bound by the Seattle Bandwidth Co-op's Terms of Service, and so are the users of madstop.org. The relevant part of the agreement has to do with pulling large amounts of bandwidth, which is discouraged.
Root keeps on file a list of all member names, addresses, and phone numbers.
If you move, make sure you tell root. This is the equivalent of my home. You are a guest here. Don't do anything bad to the machine or to other people's machines while you're here. This includes running processes that are extremely CPU-intensive on the machines that have Web or routing services running on them.
