Everyone would have it switched off if that was the case anyway so I can't see it doing a great deal of good :P
As has been said, there was a global announcement that was pretty hard to miss and was there for a week, it certainly irritated me so I don't know how you managed to miss it :P But like Jess said, you are contacted by PM before you get warned/infracted anyway so if you didn't know before, you do now!
