Randy Farmer (he of Habitat fame, and much more besides!) and Bryce Glass have been posting excerpts from their upcoming book Building Web Reputation Systems on a blog, and today’s has a great anecdote in it that hammers home all the math behind negative reputation systems.
“Hi! I see from your hub that you’re new to the area. Give me all your Simoleans or my friends and I will make it impossible to rent a house.”
“What are you talking about?”
“I’m a member of the Sims Mafia, and we will all mark you as untrustworthy, turning your hub solid red (with no more room for green), and no one will play with you. You have five minutes to comply. If you think I’m kidding, look at your hub-three of us have already marked you red. Don’t worry, we’ll turn it green when you pay…”
If you think this is a fun game, think again-a typical response to this shakedown was for the user to decide that the game wasn’t worth $10 a month. Playing dollhouse doesn’t usually involve gangsters.
