Fingerprints don't lie, but people do. As I said before.. 'He or someone else that has access to his PC downloaded and installed that hack'. He connected to a PBBans streaming server and our routine MD5 scans witch scan for hacks & hack related files found that file and kicked him, landing him on the Master Ban Index (MBI). The cheat had to have been physically downloaded and installed as files like this don't appear out of thin air nor do they get auto-downloaded from servers.
No mistakes were made with this ban. He can always appeal if he wants, but as the file's fingerprint matches the hack we have, the ban won't be removed.
