I was just contacted that helz0ne is officially closing now. Their domain expires in about a week. The good news is that apparently some of their projects will be continued by a new group, but I don't know any specifics.
Helz0ne's forum and release archive can be found here: www.bulsajo-scans.com/forum I'll add an online reader at a later time.
