EA has released the 1.05 patch for Battlefield 2142.  This patch addresses a number of issues including problems with players using game exploits to boost scores:

Today we release the 1.05 update for Battlefield 2142. As previously communicated this update will among other things make the experience better when playing Titan mode. It will also solve the transport exploit that some players have taken advantage of. Overall the update includes over 25 fixes. The fix list can be found at the end of the update.

Rest assured that we will continue to take action against players using exploits to boost their scores. We will also soon begin to ban accounts completely from online play. While we would prefer to not have to take this step we recognize it is necessary to ensure that players who use exploits and hacks in Battlefield 2142 are not allowed to continue ruining the play experience for others. As always, we are carefully monitoring how the game is being played to be able to prevent any exploits that are found.
