Warnings about swearing/nudity etc before programmes post watershed

[Ginger1982]

This really bugs me. I don't mind a warning at the start of the programme saying there will be strong language/nudity throughout etc but why do they have to do it at the end of every ad break? Surely people watching it have realised by then that there could be swearing/nudity and anyone just tuning in could perhaps expect it given the time of night? It just seems like mollycoddling.

AIBU?

I suppose incase you've turned on during the ads or half way through; to stop sensitive people/children from seeing something unexpected?

Not that I think it should be necessary, but that's probably the reason.

Maybe they're trying to persuade the foul mouthed perverts to stay tuned

But they do it for shows like Geordie Shore! Surely you wouldn't have kids watching that and, if you did, you clearly don't care what they might see/hear? Maybe it's just me!
