Recruit a Friend campaign question

I haven't seen this posted yet, so I apologize if it already has.

I have a doubt about the Recruit a Friend campaign, does it work for people that already have a FFXIV account, but that they are not playing at the moment?

So if I send the invitation to a friend, can he introduce the code and when he reactivates his account will we get the benefits? Has anyone tried this already?

I've been looking but I have not found any info on this, but if there is I'd like to know.

Thanks for the answers in advance.

Pretty sure its for new subs only. There was a welcome back thing last weekend for non active subs.
