If this DOES happen to be carded membership I would suggest that you think about the risks before buying.
If the time is removed from your account you will be forced to pay the balance of membership converted to $ through JCoins.
Personally had membership chargedback/revoked from me a number of times from pinlines/friends.
Just a thought, not trying to sales trash, if the membership is obtained legitimately and you have proof of this it'd be appreciated if you could post it; I have heard of others selling a very similar package and the way he obtained it was certainly not legal/legitimate.
