[Origin and Amazon keys for not us customers] Can you have problems?

i bought dead island two weeks ago from amazon and it was region locked...so i made another steam account and activate it using a vpn just to be sure my main account won't be blocked,but i don't know about origin...

EDIT:i use that account just for dead island,don't worry that i use it here

i thought battlefield didn't have region restrictions?

Origin is not region restricted. And also lots of steam titles working, I bought some games from amazon and I not banned. Amazon keys same N/A region restricted, but not all! Dead Island, Inversion not working, if you don't have american IP address.

I bought a Russian key for BF3 and I've had it since release.
If it activates it probably won't be a problem.

Origin is desperate enough as it is to get/keep users so I doubt they'll delete any accounts for those reasons yet, or ever.

origin didn't have region lock.. i buy mass effect 3 ru and succeed activate and play without vpn

so there aren't problems, thanks for help.
