How to limit gift cards to only new users?

[Meti T]

I want to limit the gift cards to only be used by new users (maybe with no active products OR maybe created after X date)
How can we do that?

Reason is so that my current users will buy gift cards then gift them to friends and family for the holidays.
I don't want them to use the gift cards for themselves.

Hope you can help. 
Thanks
