Steve,
Sorry, Pete, but I disagree about ignoring repeat offenders. It's by far the best way of frustrating them and not getting drawn into pointless squabbles

If you mean me Steve, I am not in the least frustrated by your silly embargo.
You could never answer anyway, and that is the real reason for it.

What is a "pointless squabble?"
A discussion where you are unable to produce arguments in support of your case!
