@stesnac @stefano from the outside: this does not look like a good policy, and an extra bad point: what is if someone a user blocked is then made moderator?

If you want that, better make one @admin and one @modteam account, distribute credentials among those in the relevant teams, use these as official communication channel to members (and eMail), and prohibit blocking those only.

(I don’t have any stakes on this, but it would be an immediate turn-off for me.)
