The Commissioner of the FTC, Orson Swindle(yea, that's really his name) introduced Dave from PC Pitstop and referred to Ben as a "Spyware Crusader". Ben said it was the first time he's been given that title, but I'm thinking it sure sounds better than zealot.
Dave presented some very scary examples of web sites easily found by kids doing simple searches. Ben followed up with examples of how reputable companies end up feeding the adware middle men which in turn feed the folks installing the spyware. There's a good reason both Dave and Ben keep getting invited to speak at these events.
