The first thing for me is: moderators must not be chosen by the community but by the "admins", as it was in the old forums

Moderators chosen by the community contribute to the echo chamber of the community itself and bend the rule in that direction, making the whole subsection more and more polarized in that sense.

Moderators chosen by the admins should me more impartial, potentially taken from outside the community itself, paid for their jobs so they adhere to the general rulebook, and keep all the sections as neutral as possible, encouraging exchange of conflicting opinions without flame.
