How can free and open source software help us fight against evil on the internet?
It tends to be data that’s needed, not software per se. However, I’m a great admirer of some of the open source spam filtering systems, they’re flexible enough to let me explain to them that I’m not interested in seeing emails that sell me Viagra, but that I’ve a professional interest in phishing emails, and money mule recruitment campaigns, so please could those not be blocked, and arrive in my inbox so that I can tell what’s going on.
