Defining a scale is not stating that there is a limit. Furthermore, stating that there is a limit is not the same as setting a limit. The one is a statement about what is, the other is a statement about what ought to be.

And even though a refrigerator can cool a place with efficiency more than 100%, the article for the "negative temperatures" advertised the "new found >100% efficiency". Who is to blame here? Is it something the article writers did on purpose? Or not?

Although Mathematicians have played around with the concepts of negative mass and negative energy for many decades I am unaware of any physical experiments which suggest such exotic quantities exist (I have already explained above how negative temperatures are not actually negative in the classical sense). To my knowledge what you are describing is much like the mythical Tachion particle which travels faster than light. Science fiction writers and mathematicians have worked out its properties with alarming accuracy, however no experiment has ever suggested the existence of such a particle. Furthermore, although it was initially found not to disobey any laws of relativity, recent experiments and theoretical work suggest that such a particle cannot exist in reality.
Or when you speak of Negative Energy are you referring perhaps to the continued expansion of the universe and the concept of either 'dark' energy or of an unknown impelling force which drives expansion? Astrophysicists and cosmologists have played around with these concepts to great effect, however neither of these represents a true negative energy. Perhaps you could link some of these articles you refer to. I personally am unaware of any kind of negative energy as you describe it.
