I think it depends on what the swear word is. Here in The Netherlands is confusing, sometimes they bleep things and sometimes they don’t. I think that’s due personal taste. For some swear words I think it’s ok but for others it’s best to sensor a little because there might be young people watching.
But then I think of my dad who was watching a gangster series last week and if they would have used sensor in there they could bleep whole dialogues. It was pretty hilarious like geez can’t they use normal works?! Why do the swear all the time?! Ohh there he goes again…
