Origin Referral Program? No!
Be careful, there is no EA Origin referral program and if you found a website that promise that there would be one, it´s not legit, it´s scam. Electronic Arts has not officially announced a referral program. It would be great if we could refer people, family members or friends to EA games if they planed to buy a particular game anyway. It would be great to get a bonus but as said, there is no official referral program until today and if you found one, it is most likely scam, so be careful.
In the past there were fake websites and they promised you would be able to get free download games on EA Origin. There are also still Facebook pages that promise the same but again, it´s not true and not possible until EA decided to create a referral program. Be careful, and never try a service that is not official. You will be most likely fooled if you fall into a trap of any fake website. If there would be an official EA or Origin referral program, they would mention and announce it on the official Origin Store website and nowhere else.
