Whoaaaa... "Players who select Withdraw from the Duty Ready confirmation window or allow the window to time out without making a selection three times or more in one day, will be temporarily prohibited from registering for duties via the Duty Finder. This count will reset every day at 9:00 a.m. (PDT)."
I guess don't walk away from your machine or register for a duty while waiting for a FATE or Hunt to pop?
