The problem I have with subscription services are this...
You can prolong the payment for 1000s of people until the subscription period ends... so a long con is possible. When things goes wrong before that, people do not have a exit to recover their funds.. and you can say that they have to wait until the subscription expire for them to claim back their subscription. (That said, the $40 per month option is a good option to test this service)
Why do we have to make use of the Proxy services, if we signup for this service... What do we have to hide?
