Thats correct, even though the risk of getting banned with referrals is pretty low, if you dont have like 1000 or more refs on one account, the gifting account method is still safer. You can simply add the gifting account with your main account and after 2 weeks you can gift the RP to your main account, with e.g. Mystery Gifts.
These accounts are mainly for people who already got some refs on their account but still want to get cheap RP
