Instead of having to implement the whole family share check thing, it might be easier to make the starter pack a 1 time purchase of a very low amount, maybe around the same price as extended tags? I feel like people are less likely to spoof stuff if it costs them money, even if it is a very low amount. Problem with that would be that it would then be less available to the newer members, I suppose. Actually, this idea has several flaws. Still gonna suggest it though.
