“Horror Vacui” aka Compulsive Graffiti Syndrome

Horror vacui is actually the “fear of blank or empty spaces” and the hyper-obsessive personality disorder a Ukrainian man named Mitasov suffered from. He covered his apartment in layers and layers of writting as well as hitting the streets.  He was university educated in economics and managed a store but unfortunately died in 1999 in a psychiatric facility.
