my only experience with blues are in the Stilton-esque style, and you don't scrape them,
you smooth them after they come out of the hoop.
I am not sure, yet I am thinking that if you scrape them you are supposed to wrap them in a special foil.
not to sure about that either.
I have read recipes that do instruct you to scrape, I'm just a smoothie (or smoother
)
