Quote from AOL:
A Fair Use policy means, for example, that we may introduce some form of network management if we feel that specific individuals are abusing their broadband usage beyond a level that would be considered reasonable. For example, using AOL Broadband 24 hours a day, every day, to continuously download large files is not a reasonable use for a residential service.
As another example, we might also manage the AOL Broadband service at
peak times to ensure everyone is getting a stable, reliable connection across the whole network. We believe that this policy will help us continue to deliver a high-quality broadband experience and that the vast majority of our broadband subscribers will benefit from the existence of a Fair Use policy.
