That's not ban evasion.. you got those evil fee to pay as a result of people who are within that your area using same IP address with you might have violated the system, they have been ban and all of that.
You need to take note that IP blacklisting will affect all countries or the VPN location used. Let us take this an en example, you use service provider A to open an account on this forum, some other people also use service provider A, and they are permanently banned, this will affect other people that wants to open an account on this forum from that country that are using service provider A as the IP addresses if service provider A is blacklisted by this forum. Also if it is VPN, the VPN per each location that the banned people are using to register account will be blacklisted.
