I fail to see how anyone could think this has anything to do with banning or unbanning. If you watch the video, you clearly see what is going on even without speaking Spanish.
Look at his error code - 2811-5001. That is not ban-related, that is due to network connectivity problems.
Connectivity problems that he created himself by putting a proxy that probably causes this very error in the first place and then he just removes the proxy and it works again. Wow, magic.
I wonder how anyone can fall for this.
