The point is that in case of teen i could understand and grannies too. What you are looking for is not clear.
But porn means you are looking for porn not sure for definition of the word porn or news about porn.
Anyway let's share our google SERP first page:
As you can see no any porn sites is listed for italian keyword "PORNO".
If i type PORNO is not the same like typing GRENNIES or TEEN there is no confusion on this word meaning.... and all people know if they wanna find a porn site must type PORNO.... this is in italy i dont know in germany or in other countires.....but is not good.
And anyway like told Goethe also typying PORN LINKS is the same story.... so this is something different.... i eman if i type porn links sure i wanna find links about porn not news...
