Regional IP blocks

I think most versions have a complete block, while Europe only blocks accounts made after a certain date. I remember when HKMS came out, everybody from Hong Kong was blocked, regardless of account age.

I'm not sure about the exceptions, but I do have a question about them.

Is there a way to play other versions of ms with a proxy? For instance, could my friend make a new account and play GMS with a proxy somehow? Have quite a few foreign friends that can no longer join me on ms because of IP blocks.

Use a VPN.
