Diouf dive

Just saw the highlights from the Blackburn v Bolton game. I shouldn't be surprised anymore but wasn't that dive by Diouf awful. A blatant cheat that resulted in a penalty which won the game. I've got to say that I don't like this form of gamesmanship, and that includes Arca's dive in similar circumstances vs Derby. I think it's time clubs stood up and took action against blatant cheaters - or am I kidding myself that such thimgs like 'honour' and 'fair play' still exist in the modern game?
