    d. We strive to maintain a high level of service, and a lot of customers
       depend on our high standards of quality. As such, we will not provide
       Services to those that are using our Services for:
    
    vii. Using the Services for a content delivery network or content distribution
         network (CDN). An authorized CDN network offered through 100TB is
         accepted. Special requests to use the Services to run an unauthorized
         CDN network may be approved on a case-by-case basis. Failure to comply
         with this policy will result in termination of this TOS, and you will
         not receive a refund of the Fees.

If you look into the TOS even more, they basically disallow anything that's bandwidth intensive.
