I visit this site every now in then to sample some hard to find music. I seen that there normal URL www.21century-mp3.com hadn't posted any updates for a while. From a different website I seen that it linked to www.21century-mp3.nu. Once I visited that I seen the big red link on the top of their page that links to:

http://www.21century-mp3.nu/main/21s...nhijacked.html

They are offering a thousand dollar reward, which I'm sure they are good for to steal back their domain. Anyone with a good amount of computer knowledge may want to take them up on that offer and hopefully also pass on some advice about securing their domain. Anyway, I just thought the AO community might be able to assist them. If not, enjoy the site.
