I see that, in the hyperbolic case, you are actively tricking your wife. I just don't agree that you are actively tricking randomly public visitors of a blog in any real way? there is no agreement in place such that you can "trick" them. Presumably you made commitments in your marriage. No commitments were made to the public when a blog got posted.

It's equally baffling to me that you would use one case to make the point of the other. It doesn't make any fucking sense.
