I'd like to give a quick shout-out or tip-of-the-hat or whatever to Peru sin Spam ('Peru without spam'), which is a site with similar goals and methods to ours. As well as covering general spam news, they have a list of Peruvian companies that send spam. Their list includes a number of the pests currently filling my inbox with their junk, including Thaisbor S.A.C., Avance Empresarial, Piramide Consultores, and Educe Capacitaciones, to name only a few (and not forgetting our old friends at Il Forno).
It's not clear how effective the naming-and-shaming policy operated by both Spamnation and Peru sin Spam actually is. Some of the companies involved — particularly the ones offering 'management seminars', who are the worst offenders in terms of spam generated — seem fairly sleazy. Still, it's nice to see someone making the effort and their site is a useful resource.
