This thread grew out of someone claiming blocking entire countries is a good anti-spam technique because they just "know" those people have nothing to say to their users. This is bigotry pure and simple, no need to go any further, they hold strong opinions that can't be objectively verified about large parts of the human population based on national origin. As someone who was on the receiving end of the "Romanian users have nothing to say to my users and postmastars there can't even RFC" blackholes, trying to get legitimate email delivered while respecting all the rules of the internet, I can only say that whomever thinks like that is an idiot and a bigot. Unfortunately, there are many such idiots on the internet at large, and the aggregate effect is that only large sites like Gmail can maintain good deliverability, which was the subject all along.
