A few years ago, when I stopped using the name “The Willpower Engine” for this site, I let my willpowerengine.com domain expire. That turned out to be a mistake: it develops that there were still a number of people using links to that domain, and some ill-intentioned person scooped up the domain as soon as it was available and set it up with a site that looked like it could be the right one, but full of terrible advice cribbed from anywhere they could find it, fueling sketchy advertisements.
As soon as I realized this, I did what I could to get the domain back, but I was unsuccessful until today, when willpowerengine.com finally points back to where it should. I apologize to anyone who may have found themselves on the scam site in the mean time.
The lesson, for me, is that retiring a domain, in some cases, is something that should only be done with great care and after the Internet has had a good long time to get used to the new location.
