It would be a lot more work, but keeping the same design and covertly moving to factual content, and rewriting/debunking the existing garbage would be an interesting experiment.

I think Dan and Jordan should get all the emails addresses from Infowars' mailing list and send out stackies full of carefully laid out dissections of Alex Jones's show. Might actually get through to a few people.
Jones should get a court-ordered ankle bracelet, and every time someone loads that website, it sends out a shock. Each shock should act as a reminder to all the misery he's inflicted on so many people.
Could do all sorts of things with it!
Accept donations for all the groups Inforwars insulted or hurt in any way.
For yucks, put up a poll for how terrible a person Alex Jones is.
