Coca-Cola encouraged Twitter users to mark (spam?) negative tweets from their friends with the #MakeItHappy hashtag, and then turned those tweets into cute art images using ASCII lettering code. Which was kind of nice, until the blog Gawker created a @MeinCoke Twitter bot that tweeted lines of Mein Kampf at Coca-Cola [19].
