I believe the term "Perverse incentive" applies here. I think many people have heard of the story of the British government trying to get rid of Cobras in Delhi, so they offered a reward for each Cobra tail. Enterprising people started to breed Cobras for a little extra income. Thus a program designed to get rid of "bad actors" actually bred bad actors. Various versions of this story have been told. Another famous one is about rat tails having a reward, thus breeding rats became popular. Write up of the above and some more examples are on Wikipedia.
