I did the blackout by changing the DNS mapping for scripting.com from the Apache server we usually use, to a Frontier server running a custom script that returns HTML with no content. It did have a web bug in it so I could count hits.
I thought it was wrong to do anything other than return an empty black page. If you tried to sell an idea or retain your rep with the search engines, then you really didn't black yourself out. I doubt if our friends at the MPAA would be so kind.
So much stuff broke on so many of my sites and people who use my software. Many of my images and scripts are hosted on scripting.com so that stuff broke even if it was being referenced from another domain. The problems rippled all through my little world. It was a learning opportunity.
Not sure why in the end I decided to go black. I don't think anyone really cared for any reason that mattered. A much more powerful way to go would have been to help people get their flow out of centralized corporate-owned media. But of course the people who own the media, some of whom were leading the blackout, would lose money if that happened.
