Because I was pretty screwed up a few weeks ago at school, my mother wrote to the mother of the one who managed our Netflix account and told her to kick me out, now I'm back in but they have a replacement for my profile found. A good friend is also in the group and would share a profile with me that would be possible, so that the "manager" does not notice? SRY FOR SOVIEL TEXT thank you in advance
If you use the same profile as your buddy, you will not notice. But if he is looking for something and you want to see something at the same time, then you can't do it, only one person can look in one profile.
If she has a clue about Netflix and IPs, and also a suspicion (that comes up when she wants to watch and it's not because everything is occupied, or if she's a control freak), then she can see that.
I think to understand your question, you first have to explain more exactly what you mean by "manager / leader / group". If a subscriber shares his password with other people, it's his problem if he can't stream afterwards.
Depending on which model is subscribed, Netflix also allows you to stream your account with multiple people at the same time. This is virtually the "family option".
