San Francisco neighborhoods have sent complaint after complaint to the city about the ads on their sidewalks and are demanding removal. City Attorney, Dennis Herrera responded to the complaints by sending a letter to execs at Def Jam Records and Universal Music Group demanding their full cooperation to identify those fully responsible for the graffiti.

In the letter written by City Attorney Dennis Herrera it stated that,

"illegally exploits our city’s walkable neighborhoods and robust tourism; intentionally creates visual distractions that pose risks to pedestrians on busy rights of way; and irresponsibly tells our youth that likeminded lawlessness and contempt for public property are condoned and encouraged."

Representatives for Universal records has not responded to the letter or comments.
