I have to agree that most of the responses in this topic really do make it seem like the moderation team isn't actually interested in feedback, which is discouraging.
My complaint is with over-moderating. I fundamentally disagree with the assertion that every instance of a minor infraction needs to be called out. Sometimes All chat is completely civil but then somebody writes 4 extra letters in a word and a mod jumps in to tell them not to do that. E.G. The person might say "Whaaaaat?" as a way of expressing disbelief and the mod will remind All chat not to spam excessive letters. At this point, the chat will become derailed as people are more concerned with why the mod is wasting everybody's time than with the original topic. That kind of moderation has the exact polar opposite of its intended effect. Rather than keeping chat clean and productive, it causes it to degrade and become more chaotic. And for what gain? I'm not talking about somebody spamming 5 lines of letters; I routinely see mods chime in because of a single-digit number of extra letters as if it's spam that is making it harder to read chat. It's not.
Similarly, the people who help in Help chat should be allowed to be humans for a moment here and there. Maybe I've just helped somebody with something difficult and they are trying to wrap their heads around it and I'll tell them "Yeah, I struggled at first, too. One time, I even had x happen to me. It was nuts". Technically my last couple sentences are 'not help' and belong elsewhere but at the same time they keep the channel feeling conversational and human. If a mod then tells me to keep it on-topic, they aren't really helping anybody. That doesn't improve the quality of help anybody gets or their ability to ask questions and be heard. It just makes everything awkward and sometimes it chases away the people who are actually there to help. I spend less time helping new players than I used to because of over-moderation of the Help channel.
