MFONE
MFONE is the nom de plume of Daniel Montano, an artist and graffiti artist and who was active in Pittsburgh in the mid and late 2000s. At the peak of his tagging activity, he was considered to be "the most notorious tagger in [Pittsburgh] history." According to police, he is the most prolific graffiti writer in the city's history. He replaced Mook in local graffiti folklore. His graffiti activities are alleged to have caused up to $713,801 in damage.
A member of the Pittsburgh Police's Graffiti Task Force said "Montano has real talent; he's an artist. These other guys are copycats. But they're all vandals." MFONE's artistry was so well-respected that subsequent taggers have been referred to in the media as "no Daniel Montano."
