I withdraw my question and I am sorry. I do know that it is not allowed to ask about "cracked" stuff here or on any other original MC forums.
I did not want to talk about piracy or anything. It is just that I do have original MC, for 2 years now, and there are some who do, but some don't.
We will find our own way to protect the server, thank you for trying to help, and if you would be so kind, do not ban me, as I will withdraw my question. Thank you.
