Duffman has legal steam... not cracked.. Casper did great job by providing this demo and he has cuts. But he aint hacking, you should little bit ask other admins opinions. Share you demo in admin section that other people can review before you will ban him. That's will give you more opinions of other admins and high staff. Just with experience you will get it right Casper, none has nothing offence towards you..
And if you are people coming here to attack our admins, well you could always apply in same position and show yourself how are you as admin. I respect highly active admins if he bans over 10 hackers per day ban one pro player. Community wins.
PS. I suggest for us all. Leave Duffman play in servers because he is clean. But of course you can records demoes.
