Oh! THANK YOU, THANK YOU, Tatiana!
The "shunning" one is called The Invisible Man
I thought of the DF'ed ones even way back when I seen this as a kid...LOLCotter Smith is Mitchell Chaplin, a man living in a parallel world to ours, who has committed the crime of coldness. According to the state, he is to be rendered "invisible" for one year, signified by a scarring implant placed on his forehead. What seems like a welcome chance to be left alone becomes a lesson in humility, as misfortune after misfortune befalls him and he can't even get medical care; despite his attempts to conceal it, the implant warns others to ignore him, lest the hovering spy drones that monitor their society find out.
