The San Francisco City Attorney’s office is going after Zynga for an “illegal and actionable” marketing campaign tied to Mafia Wars: Las Vegas. Zynga had glued fake $25,000 bills to sidewalks in San Francisco that directed people to a Mafia Wars website.

“The City Attorney takes violations such as these very seriously, and intends to pursue every available cause of action aggressively against Zynga for these illegal marketing tactics,” writes Deputy City Attorney Alex Tse. “[Zynga must] provide the City full information regarding the nature and extent of the marketing campaign affecting the public way in the City, identify all parties other than Zynga responsible for this campaign, and provide the City with a proposal to fully resolve the issue.”
