[Plugin: NukePiG] Doesn't seem compatible with multisite

Hello,
Thanks for your plugin. I tried installing it on a WP Network to delete content from one of my sites. Although I used it from that child site, the parent site’s content got deleted instead (I had made a backup).

Can this plugin be used to delete a child site’s content?

Thanks,
Jayce
