An AcceptableUseAgreement is a statement by a service provider about what constitutes acceptable use of the service. Typically users must accept the AUP in order to use the service. Some service providers have more liberal freedom-respecting AUP's than others. Comcast is an example of a service provider with a particularly freedom-hating AUP. We recommend avoiding them when at all possible. Generally speaking, local ISPs have more freedom-respecting AUPs than behemoth national ISPs..
