I had to add the delay after a bad apple repeatedly uploaded copyright content via VPNs. The delay allows me and selected copyright holders to be notified of certain uploads before they go live, so they can be checked and dealt with without ever being visible to the public. Ideally the old version of a deck would remain when the deck is altered, but implementing that would require a considerable amount of extra work. There is no way to bypass the delay, but it will eventually go away when your deck becomes old enough.
