I think people are missing what's actually going on. People don't give a crap what the vulgarity function is for, they just use it to hurt or get revenge on people or realms they don't like. And if the reported messages goes to enough people in realms who dislike the realm/side the message came from (which is often discernible from the message itself when dealing with insults in war), then they vote it vulgar.
That should not be an assumption, merely considered a possibility.
