Hello Hobo Gamber,
I have just been looking at the reason behind your ban, It states within our logs that you scammed STEAM_0:1:172001503 for 70m on 30/10/2018. For you to be unbanned you would have to repay that 70m to such user. If you would like to be unbanned you will need to contact the user who you scammed and repay them the 70m. This can be done with other players paying the 70m then yourself paying them back once you are unbanned.
The steam account of the person you scammed -
