It's possible that the Curse only affects those who have set foot on FTL. That would include Mad Hatter, Cora, Frankenstein, Smee, Hook and the Giant. Which at the time of the Curse may have been in other lands.

Frankenstein was in Storybrooke, even Regina didn't seem to know why he was there. (But she could of been lying).
