Question

So i have a uplay account (steam version one) but i don't have steam account that have r6 to launch the game.

If i borrow my friend's steam account and launch r6 of my uplay account, and i was banned for some reason, does it ban the uplay account linked to the steam account I use to launch?

You can choose not to link accounts in uplay settings

Once i unlink my friend's uplay from his steam, his account should be safe right?
