This didnt take long

Thank you for sharing.
I suggest everyone avoid QUICK MATCH and look at the servers friends are playing on before joining them.  We are responsible for our own actions.  Use the server browser for 32 player Metro servers and ask someone on TS if you have a question or concern.  DICE already announced they are monitoring any 3rd party software players are using (PunkBuster is not active).  We should be in good shape for launch.

And they will do it too!!!

My Account got hacked in BF2 and then the account was used on a "Compromised Server", and as Wolffang will tell you...I was uttering some not so "polite and friendly" words as I watched my account being removed from the system by EA.  I was not totally banned, but EA reset all my stats to zero after 2.5 years of game play!  I see they are now taking it one step further now and banning rather than resetting an account. (Hopefully this will cut down on those wanting to ruin the game for everyone else, because the a reset meant nothing to someone who was out to wreak havoc)    I am personally glad for this extra protection to ensure a good gaming experience for BF3!!

That video at the end of the article was nuts!
