Right, on GitHub and IRC, people with “administrative power” can moderate;
However, they are not explicitly identified as “moderators”, i.e. persons to reach out to for help when something feels wrong.
On the other hand, on Discourse (thanks for pointing it out), and Discord (I just checked), there are people with this dedicated role.
IMHO, this (who are moderating each platforms we interact through) could should be explicited somewhere.
I will mention this in https://discourse.nixos.org/t/draft-community-manifesto .
