So the reason I banned him was the WAY he said it not the swear word in general.
I don't see how this corresponds in any way; at this point I'm just thinking that some people are making up stuff. The server rules state "- Keep offensive language to a minimum.". So you can say fuck off in any tone but keep it to a minimum.
So this either gets accepted by the fact that that was the reason "because of his tone of voice" or that I'm missing a great factor.
