cheaters prove that EA's security system is very, very bad

You do understand that posting screenshots with usernames/IGNs is against the rules (naming and shaming), even if it's obvious who the cheater is. The best course of action at this point in time is to report them in the game and move on. While cheaters have been a persistent issue, it's clear that they are being gradually removed. However, the bigger problem is that banning their accounts doesn’t stop them from creating new ones and continuing to cheat, only to get banned again, and the cycle repeats.
