While the high levels of cheating in Battlefield 3 might have been curtailed to some degree since its launch on various platforms, it's still a problem and the "report" button on the game's Battlelog is a button push that leads to nowhere. Well apparently EA Dice has finally decided to fix the problem, if you believe this brief report on fan site BF3 Blog (for the record, I do).
According to that report EA Dice has improved the "Report" function to let users report cheaters and "stat padders," and also allows them to submit links to Battle reports, and select a player that is suspected of cheating. DICE is also promising that someone from the studio's anti-cheat team will "manually" check reported individuals.
