Hai user.
We've issues with banned users creating second accounts and the using VPN (a "device" that allows you to move your IP address to another place) to skirt detection. It puts us mods in a difficult situation. So we have decided to ban suspicious accounts found to be using VPNs. So basically it's a 2 step process, first you look suspicious, then we check your IP. If your IP proves to be run through a VPN, it's possible for you to be banned.
