NFS Carbon Spyware?
Electronic Arts probably sold the rights to serve a contextual in-game ads based on a player's physical location (based upon his or her IP address). If you look into decrypted version of NFSC.EXE you can find strings like locate.madserver.net, AdClient.csv or AdClientLog.txt which leads me to similar conclusions as the Battlefields 2142 players earlier.
The MADServer.net domain is currently owned by Microsoft corporation. What's the funniest thing that the publisher (EA) probably gets only $1-2 bucks per each sold title... I wish they would make the game $2 more expensive instead of doing this unpopular decisions. Problem is that the people are sheep and most of them actually never realize that they're being spied.
Currently the easiest workaround for this is to deny the resolution of the madservers.net addresses in the hosts file of your OS. See NFS Carbon FAQ for details on this.
