Can inmates use Facebook?

Inmates do NOT have access to the Internet (unlless they have a smuggled smartphone which is highly illegal but more prevalent than you'd think), therefore they don't have access to Facebook. BUT, there are small businesses popping up where an inmate may pay for a person on the outside to update their social media pages. Or it can be done without a fee if someone (maybe a family member) is willing to do it for you. Using Facebook through Trulincs or other prison email services circumvents the prison mailroom. All over Facebook, Instagram, and Twitter, prisoners are posting photos of themselves straight from the penitentiary, with all their tattoos and gang affiliations displayed for the world to see. People in the real world are friending and following them, liking their posts and leaving comments, creating feedback and a dialogue with those trapped behind the prison walls.
