The IP ban (Like in most JP games) apply to anyone playing from any IP other than one within Japan. And have fun playing through a VPN, if the lag doesn't make you want to quit, the fact that Japanese VPN's get shut down fairly quickly in some cases.
Any VPNs that work with Proxifier or Super Socks5Cap? I get connection errors on private proxies.
