Here's a classic example of a spammer: http://www.androlib.com/android.comment.author.anonymous-qmCD.aspx The guy has posted dozens of spam in multiple app reviews. How can we report individuals who post spam in reviews and clutter up the marketplace? Can these individuals be banned from the market place? Android needs to put a stop to market place spam before it gets out of hand. Otherwise it may end up like email where 80-90% of all content is spam.
