There doesn't need to be any system to it - if you don't want a bunch of ebots, simply turn off notification from your edit favorites page

To be honest... I really don't like the idea of adding members to fav list :blushing:
And if I turn of ebots... why to add members to this list? :P
I'm afraid that this adding to favs can turn this cool project into another clique in a blink of an eye ...

I really think that a simple tag {Critique Club} in notes, under a pic could be enough. It would show  the rest  that we're part of a club, and we seek of honest commments.

Maybe they want to post now, when they can count on some honest opinions?
