“Activists estimate that half the billboards in New York City are illegal. Between fudged permits, lack of enforcement, and millions in profit, outdoor advertising has become a corporate black market that wont flinch at breaking laws to get your attention.&helip; IllegalBillboards.org is a new effort initiated by the Anti-Advertising Agency with IllegalSigns.ca to help organize and support the removal of illegal billboards in New York (we’ll get to the rest of the country soon I hope!). IllegalBillboards.org consists of a forum and blog where you can learn how to investigate an illegal sign and track progress.&helip; Canadian activist group IllegalSigns.ca is responsible for the removal over 100 illegal billboards in the City of Toronto.”
