Some spam-blocking services give the option to block all incoming email
from certain countries, such as China, Korea, several African countries,
and, I'm sorry to say, Brazil. I presume these choices are available
because of the relatively large amount of spam compared to the small
amount of legitimate email originating in those countries. (A noticeable
fraction of the 200+ spam messages I get each day originate in Brazil,
but very little legitimate email does.) But I don't know what purpose
would be served by preventing a web site from being accessed by people
in those countries, unless it's concern about a denial-of-service attack
by a virus or worm being sent from there.

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?

I'm in South America and can access qsl.net without problems.
Maybe it is because my ISP has an IP-address range within a US ISP's
address pool.

Kind regards, Eike
