Bitcointalk has a total board of about 240
With an average post of 8018.93 posts per day.
And an average of 322.94 topics per day..

How in God's name are the moderators going to handle about 300 pending posts all on their desk, considering the fact that they also have issues to handle in real life..

It's going to be life draining for the MODS and just cannot be implemented
There are other methods to draw their attention to spam/plagiarised posts, and that's the "report to moderator button"

Instead of literally killing the moderators with more work to be done it'll only be fair if the community(@OP you included),contribute their/your own quota by searching for or anytime you come across something fishy,check for plagiarism/spam/copypasting and call the attention of the MODS

MODS are humans also
