insults, like this (in a comment made to a user whose first name is "Karthik"):
@Kar Thick - please read out FAQ so that you understand the nature of this site before post anything at all.
My style might not be as smooth and welcoming of stupidity and laziness as some, but I do try and make it a point to play the ball, not the man. I'm fairly sure I've never "creatively" mistyped a user's name to turn it into an insult, and if I have, I'll make a full public apology, directly to the user involved, if necessary, for having done so.
I flagged for mod attention, but then I decided, given the recent "war on snark", that it was worth raising here for wider attention and discussion.
