These codes were easily broken because anything ws consider a crime. For example spitting on the sidewalk, talking too loud, public intoxication or not stepping off the side walk when a white person was coming across your oath, were all consider crimes and would result in a conviction.
Once convicted and charged, court fees would be given to add more to the given sentence. Even innocent blacks were pulled of the streets and placed into the convict lease system. Convict leasing was basically just another name for slavery.
However the conditions were hoffifying. Approximately 800,000 blacks had fallen into incarceration due to the black codes and pig laws. Aboult half were enforce in the convict leasing system. 9000 of those in the convicted leasing system died before their realse due to diseases, lynching and harsh working conditions. They were literally worked to death.
