no repercussions? lol, you are aware of what online piracy is correct? alone posting it broadly and publically online is an aweful idea. that would be like going on facebook on a public account and telling the world your cheating on your girlfriend/wife. it will more then likely come back on you. i'm not sure if your aware but piracy is a pretty heavy offence in almost all countries leading anywhere from a $250 USD fine up to 10 years in prison. just saying, be careful and that there can be repercussions. why risk a $250+ fine for a game you could spend only $20 on.
If it's directly downloadable on minecraft.net then it's no piracy.
It's mojangs fault if they accidently give it away for free.
