This is an extract of paragraph 2 of section 1 of the Stack Exchange Terms of Service:
...Subscriber also certifies that they are legally permitted to use the Services and access the Network, and takes full responsibility for the selection and use of the Services and access of the Network. This Agreement is void where prohibited by law, and the right to access the Network is revoked in such jurisdictions...
Does this mean that it's a violation of the terms for the Subscriber to circumvent blocks that the Subscriber's country imposes to access the Network?
