Most NBA fans are aware of the new flopping rule that was imposed this season. You can find details about it here. The basic idea is that whenever the NBA determines that a player has flopped, he gets a warning for the first offense and a fine for the rest.
Most of the time, I get news about flopping via articles on the web (e.g. here and here), but is there an official web page that contains data about the full list of those who have been warned or fined? I couldn't find one by doing a brief search on ESPN or NBA.com.
