Does a signature campaign organiser come out to find a good poster?
As far as I know , signature campaign managers do not find or look for posters then make good offers. They just let someone apply on their campaign thread then will review their posts and that's it. They will then decide who will be accepted and sometimes choose someone who got a good post quality then will give special offers
