Theres a few reasons why peanut that i have come across, the main and initial one was outrage from victims groups, one woman in particular lobbied and made a lot of noise about how her murdered loved ones life was cut short and she felt it was wrong that offender is online seeking love saying how he likes cats that he should be exluded from that as part of his incarceration, i believe thats where it all started, it wasnt in florida though they just jumped on the band wagon.

Secondly i do believe that us pen pals generate a substantial work load for any doc, the cost cutting aspect would be attractive.

The DOC can pass a rule that apparently affects the inmate but its not actually a law, therefor anyone can post an add on their behalf, from my understanding this DOC rule has been thrown out of other states because it voilates rights
