The blogger id:hagex was murdered by a coward.
He was thus not able to renew his domain names. I tried to acquire them recently so that I could preserve them and fix the images on his blog which have broken, and then perhaps transfer it to his family at no cost.
After much searching, I found the company controlling them. However, they wanted a large amount of money (if I remember correctly, ~$12,000, or ~1,332,342 JPY) for the domain hagex.com, which I found distasteful (and which I cannot spend). This price was given after the background of my request was explained, so it was not made in ignorance of Hagex's murder.
