Heaven's Gate – Official Website
The Heaven's Gate homepage is unquestionably the 'deadest' website on this list. (i.e. – nearly everyone involved in its creation is dead.)
For those who don't know the story, Heaven's Gate was a religious group of Californian ufoligists who committed mass suicide on March 19, 1997. The date coincided with the appearance of Comet Hale-Bopp in the sky, which followers believed was a spiritual portal to another planet. Over a three day period, 39 people took their lives by ingesting poison mixed with apple sauce. They were found wearing badges which read: 'Heaven's Gate: Away Team.' (We wish we were making this up).
Bizarrely, the cult's official website is [[xref:http://www.heavensgate.com/|still up and running]], some 12 years after the events transpired. We're not sure who's paying for the domain name, but its contents are a chilling testament to when cults go bad.
Here's an extract from the site's final entry: "Our 22 years of classroom here on planet Earth is finally coming to conclusion – 'graduation' from the Human Evolutionary Level. We are happily prepared to leave "this world" and go with Ti's crew." ...Just say "no" to wacky cults, kids.
