Unfortunately, I would also prefer it to be but I think there are sometimes you need to weigh up the options as a mod/knight, and we can't be so quick to assume anything. As I mentioned above, I have seen plenty apologize and then continue on nicely and tip. Another thing is, I have seen people do this because they have some kind of arrangement/agreement with the model (via PM or pvt) that they can do it (which I would say they still should not do openly, but that is not up to me either way). And I am sure there are other reasons, so I can't be so quick to judge and mute, even though it may seem so obvious to be. But after he didn't apologize (I was hoping he would and not make that dumb second comment, because he had only joined a few days ago and was a rank 18 I think so had spent), I did instantly and without hesitation mute.
