Why would you need that? There is no credit steal item anymore, so no need to store them on another account.
I usually do that when i have quite alot to stop people from asking me for credits, i used to get that all the time, so i made a new account and sent them there
And there are logs to tell where they sent them. They are allowed, I just dont see the point. If someone asks for credits and you dont want to give them away, just say No.
