Rejection criteria idea
No clue where to put this... but any chance that "No demonstrated historical or cultural value" could be added as a rejection reasons. I like the word demonstrated because it tells the nominator that such value might actually exist but they have done nothing with the title or description to indicate this.
For a lot of places I reject, the reason is that, often coupled with it is grafitti where it isn't likely to be there long. (When someone has tagged over a piece of grafitti art in a question if legal place...) are often my main reasons. Or could be.
And not sure if in those cases, i shoild really be giving a 2* up top and 1* in that category in order to givw the best feedback to nominator.
