banned you temporary because multiple people were complaining. As you can see at https://banlist.kandru.net/banlist/bfbc2 you have been unbanned after 600 seconds (usually using that time off for people I'm a little bit unsure if they've cheated or are just good).
If you haven't used any tools for aimbot/wallhack etc. then I'm sorry for banning you. If you did use tools please don't use them.
Have fun playing on our servers but please stick to the rules
