EA has released more information on their anticheat. They've renamed it to Javelin and claim their bans are 99% accurate, which I don't believe.

At the bottom if the webpage there's two links that explain the review process for cheat bans, text chat bans, and voice chat bans. It explains when humans decide the ban and when AI decides the ban. For voice chat a human always listens to the voice recordings and EA records everything you say and type.
I'll never trust or believe that any anticheat is stopping cheaters. I've been online PC gaming since the 1990's and I've always seen cheaters in online games. The amount of cheaters has only increased and gotten worse as time goes on.
Gaming on PlayStation with PC crossplay turned off is currently the best way to play online games with the least amount of cheaters. Unfortunately Xbox makes it difficult to turn PC crossplay off compared to PlayStation.
