The picture above shows me and my friend who bought me the code.
The date was August 30,2012.
Well you posted the key and it's been shared by minimum 3 people so it's long gone but if you really didn't give it out to anyone but your brother and he really for sure didn't give it out the person who did give it out is quite obvious:
You just said your friend who bought it for you posted the key to you on facebook which means he is the actual original owner which means he is the one that is using it or gave it out.
I'm not entirely sure but I'm pretty sure Blockland has the option to buy it as a gift for someone and it gets sent to their e-mail so only they know it, buying a key for someone else but buying it and sending it to your e-mail and then copying and pasting it to them is not allowed and is the same as key sharing.
