This can not be under-emphasized. I was in my late teens/early 20s at that time and a lot of my friends who were nerds and into the rave scenes had stories that started with "Oh wow, I met Captain Crunch at a rave, we'll get to hang out soon!" and ended with "You are sweaty, you should take off your shirt!" or "Do you want an energy transfer massage?"

I first met him in '00 (I think). He came up right after I played a live techno set in a warehouse in Oakland, and I second this. As someone who grew up on 2600, my excitement for meeting Draper quickly turned to backing away once the topic of an energy transfer massage came up.
Seriously. It's like this article tries to tug on your heart strings and make the reader want some justice for this early pioneer in tech and then totally never mentions that he's even more famous for being a total creeper.
