I honestly see absolutely no benefit except for people to put their noses where they shouldn't be. I'd rather ATA focus on developing other aspects of the game. Ie. Organizing our trade section (o pretty please apes?)
Idgi. How would this help? A. T. A can literally see all transactions people make from their accounts so if you point out a scamming alt and they see it trade a tonne of stuff to a bigger account for nothing, they may be able to identify it as the main and ban it. That's way better and more reliable than whatever this solution is. Also, now, they can freeze the items on accounts and prevent them from being traded.
I think is good because what if your not allowed to access your account and you make a new one and you search your last account then you can add the friends off your old account
