In fact, if you use a computer system to commit a crime, you are exposing the operators of that system, and its other users, to legal risks that should be yours alone. If you genuinely do not know whether something you would like to do is legal or unlawful, please discuss it with us before you proceed. And if we tell you we do not want you to pursue your plans on our system, please respect our decision. Respect the security of our system. Do not try to gain access to system areas private to ourselves, or to other users.
Some users try to crack system security just to show it can be done.
Do not try to prove this on our system. Do not run unattended processes or servers. These tend to put a load on the system unwelcome to other users, and often have a tendency to cause server reliability to decrease. This includes Muds, MUSHs, web servers, IRC bots, etc. Do not connect to more than one dialup port at a single time.
