We have seen, here and observing elsewhere, that moderators who do not engage with the community generally lose touch, and seem even more arbitrary than moderation usually does. YMMV, but that's our opinion
Given the above - whatever account we are using, we'd be in discussions. This is most obvious and transparent if we use only one account. The failure modes of not being open about this are pretty bad. At least this way, you don't have any question of who you are talking to.
When we are speaking "as moderators" we use colored text. And I generally put "Mod Note" in bold at the start of any such post, for the benefit of those who might have color blindness.
Then don't. You are free to not engage with us as individual posters. We don't take any offense at that. There are hundreds of other people on the forums to discuss things with.
