I would think in that setup you'd have to have it such that you subscribing for another person would not guarantee that another person would subscribe for you. In other words, some people subscribing for others would not receive a subscription themselves, and some people _not_ subscribing for others would still receive a subscription paid for by some other user(s). Basically, you'd pay for a subscription and the benefits would go to some random user that is not you.
