Spanish Internet Provider's SMTP traffic Blocked

Andrew D Kirch writes "After being barraged by spam and 419 scams from Rima-TDE and telefonica.es [translated], the AHBL has announced that all of Spain's national ISP's e-mail will be blocked by their blacklisting service. One has to ask though, is blocking an entire country like this the future of spamfighting, or has something gone horribly wrong?"
