It may be that my postscript to the second email worried them:
Please make sure you follow the comments in this post. It is apparent from the tables of contents of recent issues of ZNA that Ji-Huan He has been responsible for the increasingly bad quality of papers accepted into ZNA. He is destroying VZN as you sit idly by.
Maybe you don't care about journal quality. That's hard for me to understand, but perhaps you're just cynical. You should at least be concerned for your jobs. A journal this bad cannot exist indefinitely.
ZNA is number 18 on our Master list of Ji-Huan He's editorial positions. The entry has been made red to reflect the firing.
