RAF level granting

[MiRai]

Correct. However, existing accounts can still be used for the Recruit-A-Friend program for up to 30 days after creation. As such, it's possible to set up a closed loop, where every new account is linked to another new account - effectively making every account both a recruited one, as well as a recruiter.

People reported this in the beginning of the new RaF system revamp, but I know someone that recently tried to create the 'closed loop' recruitment and was unsuccessful, and upon contacting Blizzard for assistance they said it was not possible. So, I'm going to assume that it was unintended behavior from the beginning and just something that was overlooked when they revamped the system. Unless the person who recently tried it was doing it wrong. /shrug

EDIT: It seems the person I'm referring to did link their accounts incorrectly, so a full circle may still be possible.
