This is my question too. If I am going to risk my Google Account getting banned, there is no way I want to try something like this. If it is actually explicitly allowed, then sure I will use it.
I don't think it allows you to login with your Google account. You can have a local account on the instance but it does not have anything with your google account.
So you cannot interact with videos (comment, like..etc) although you can create Playlists that will be linked to your local instance account.
