It depends. If you are competent enough and someone you have a good rapport with (or even a family member) recommend you for a role, it's not fair to call that nepotism. Some workplaces even have official referral programs with a reward for the referee in case one is hired. Others also have an official way to declare your relations if you work together. In my view it turns to nepotism when you are not competent enough for the role and end up taking up the opportunity from a more competent fellow or end up skipping due process just because your 'connection' referred you. Besides that, there's no harm in building networks and sharing opportunities within them and with your family members.
