Hi there, I'm a user of a gaming client called Ranked Gaming (RGC). Recently I got an account ban, IP ban, and server ban (or client ban, I cannot remember the detail). Even if I change my IP and Mac address, the administrator of the site could still track me and ban me immediately. I'm so curious about the principle behind it. How could the admin detect and track me and get notified? I tried to Google it but no useful comments. Anyone here please help me? Thanks
