Urinal Marketing

[Catwoman]

The cars and cards thing... such advertising is unlicensed and if you caught someone you could prosecute them for polluting public space. You wouldn't win, but you must protest!

The most effective way to eliminate unwanted advertising is not to buy the products, ever. Buy unbranded, organic, natural stuff that is not mass-marketed and while a gigantic advertising onslaught may follow to recapture some customers they will give up in the end, because advertising is always the first thing to go in a budget. They'd rather spend it on logistics, or lining their own pockets.

Hate to say it but spraying/knifing doesn't really help because they will just put it down to mindless vandals and replace the ads, and you've wasted paper/ink/aerosol/time. If you are going to deface things at least write something symbolic like 'I was born on Madison Avenue' so they get the message.
