1st of all i dont want to explain how our system is working. If you go to bank and ask how to rob them, i dont think you will get an answer. Also logged from dynamic ip is not proof anything because still i dont know why did you download same file many times a day.
We know about dynamic ip but we are not going to tolerate downloading own files. I can understand 2-3 downloads, but there is a lot more.
As you can see in this thread we paid to many users, and we are still paying. I think it is the best proof.
