Wars between crime families are one thing, but when you wrong New Yorkers and don’t offer an apology—especially after you made nice with people from, ugh, California for the same thing—you could wake up with a lot worse than a horse’s head in your bed.

The blog East Village Feed is doing battle with Zynga, a California-based video game developer that peppered the East Village with stickers promoting its new game, Mafia Wars. The blog’s editor wrote a letter to the CEO of Zynga saying, “I’m not sure if you’re aware—but there was recently a large promotional campaign throughout NYC’s East Village to promote your new Mafia Wars game—dropping stickers on parked cars (http://techcrunch.com/2010/08/05/zynga-mafia-wars/) and ‘dollar bill’ stickers on the sidewalks of the neighborhood. While I’m sure these stickers were very effective in the short term for your promotion, they are now unattractive, illegible eyesores. Are there any efforts by Zynga to remove these?”

So far an answer hasn’t arrived, but let’s hope the Zynga people figure out what they’re going to do before any mysterious accidents occur…
