Anti-farm code

I have a great idea....why not do just as the pop up says and play the area through normally. I mean thats what the windows says. All this other stuff that people present as facts is pure speculation. My guildy and I tease each other that our accounts must be heavily flagged for farming when one gets a cool drop and the other one doesn't. I farm a ton. I have gotten this code a couple of times. I have no idea how to reset nor will I preach to have the solution. Lets face it we will never know how to get rid of this code, they don't want us too. So do like the sign says and play normally for a while.
