So I'm back home from the 2007 EU Spam Symposium which was held in Vienna in Austria and you can grab my presentation here . You'll notice that the presentation template is from MailChannels . They very kindly sponsored my trip to Vienna and so I did a little publicity for them. There's only one slide, however, that's actually anything to do with MailChannels in the entire presentation, so don't expect a product pitch! One thing I didn't mention in my talk was that as the number of Internet hosts expands and the number of broadband subscribers grows the number of competing botnets can also grow. That means I'd expect to see the price of botnet rental dropping as the Internet grows leading to lower costs for spammers. I'll give a complete round up of the conference in my newsletter next week, but overall there were some interesting talks, and meeting some people like Richard Cox from SpamHaus and Richard Clayton was very useful.
