Concerning rejection notices:
helper, I understand why what you suggest would be very valuable to spammers, and indeed they are always spammer's top priorities. It is essential for spammers to know immediately how we detected their deception, so they can immediately change their strategy and not waste any of their own valuable time submitting spam we can easily weed out.
On the other hand, it's absolutely useless for submitters of legitimate sites -- you know, the ones we actually want to have more of, and don't reject.
I can see why this is important to you, and certainly there are many who will agree with you. But I'm completely puzzled as to why you think we're so extraordinarily stupid as to want to implement something that helps spammers hurt editors, but doesn't help submitters of legitimate sites!
Concerning editor quotas:
It has been said before and needs to be repeated until the message gets across: We are editors, not submittal reviewers! "Our priority is to build the directory!" and a directory-building editor who doesn't ever look at a single submittal is a valued member of the community. This is the official word, and the Editor-in-Chief says it often enough that it could be taken as the official motto. I couldn't change it if I wanted to. Not that I'd want to.
Editors' priorities are one of our most valuable assets, and we will not let site suggestions deprive us of that valuable asset.
Which part of that haven't you heard before?
