No, but if you're saying the proposal is bad
because people suck, then
AGF does come into it.
Not people in general, just some people. AGF only applies when there
is significant doubt. There is no real doubt that a "nominate this
article for deletion" button would be abused. How much it would be
abused and how easy that abuse would be to deal with is a little
harder to determine, so it might be worth giving it a go to find out
(this is a case where experimentation won't do any great harm).
