Sittenwidrig

I am translating guidelines for company internet use from German to English, and have come across the word "Sittenwidrig" which translates as immoral. My German boss believes you can prevent people from accessing information on the the internet that is "immoral", whereas as I believe that what is immoral is subjective, and to put it in the internet use guidelines would be pointless.

Does anyone know any other translations of sittenwidrig? And has anyone ever come across internet guidelines preventing ppl from accessing immoral info?

In legal terms, sittenwidrig also means anything that breaches business standards or is against public policy. For example extortionate interest is sittenwidrig.

How about "against common decency"?

EDIT: I agree with Sarabyrd and would go with her two suggestions...

'Immoral' is definitely too subjective; you could try 'indecent' or 'improper'.

What about "unethical"?

Basically, think pictures of naked ladies. I don't consider that to be "immoral" or "unethical", but I agree that it is "indecent" in an office environment. This is why I work from home.

@ STB,

Haha, yeah thats it exactly, not immoral but probably indecent. Cheers for the suggestions everyone.

inappropriate? although all of these words are subjective..

Inappropriate is more "gegen den guten Geschmack", still a debatable question, sittenwidrig is kiddie-porn.
