I'm not using "swearing" as a euphemism for doing worse things. I'm saying that because it's – not exactly but I thought on par with – the example given by Square Enix in their rules under the drop-down points for "Offensive/Indecent Expressions".

Example 1
If all members of a Free Company think that "slightly vulgar jokes are not a problem and will not cause offense", then using expressions that fall under the category of "slightly vulgar jokes" in the Free Company in question will not be considered a violation unless it is reported.

However, the perception of "slightly vulgar jokes" varies from person to person, and there is the possibility that what you consider to be "slightly vulgar jokes" may be considered unacceptable by others. Please be careful when making these kinds of expressions.
If the owner of the house going to permit a thing at all so long as everyone in the room is okay with it, then they shouldn't be the ones in trouble when a new person enters and doesn't like their discussion.

Conversely, if the owner is not okay with that discussion happening in the private room whether they can hear it or not, then they should make it a blanket rule that you can't talk that way and in all situations you do so at your own risk.

Allow it in private discussion, or don't. Not a vague "you can while you think everyone is okay with it, until you unexpectedly get reported for it".
