I would say yours was just a little more pointed, but I agree that it still falls under constructive criticism. I also think you’re doing the right thing continuing to try to get a response out of the original moderator in case they did this in a fit while having an unrelated bad day or something. We never know what’s happening in people’s lives outside the internet, and maybe they were dealing with a death in the family or who knows, just something where the stressors added up and this stress of moderating became too much to bear when faced with constructive criticism. They may come back in a day or so and regret their decision, which is why it’s good of you to keep communications open. Cheers, mate.
