Ok everyone here stop whining picture this, how busy would a moderator be if they have thousands of people playing their game and millions of unread posts, there will always be delays and even for days, your plugins will eventually be approved or either disapproved, just wait.
That's exactly why I said that admins should invite more users to the group.
They need strong trust to invite a new moderator, requirements probably are lua knowledge and other stuff that we don't know, they can't just go inviting random members to be a moderator.
What is the use of knowing LUA to approve/disapprove a plugin?
As for trust, I think it would be enough to choose someone who has always made quality plugins or invite users at will and teach them to be good plugin moderators.
