Hello,
It has been almost a year that I cannot access QSL.NET.
It's not ISP problem, because I've tried at some friends house, and
they could not access as well.
It's not virus problem because I have formatted my PC.

I've heard that QSL.NET has blocked all access from South America. Is
that true?
Why?

This is very selfish of your part, Mr. Admin from QSL.NET (if for
coincidence you are reading this post):
My Radio-Amateur friends an I have always used QSL.NET as a way of
research, look for another ideas, and communicating with other
Radio-Amateur via internet.

You have just cut our access to the server.
Will this selfish and Infantile conduct be forever?

Thank you very much,
Hayato
