When a game has hundreds of thousands of concurrent players and a market that constantly demands more and more cheats, it’s almost inevitable that you’ll run into cheaters. EA themselves have said that their anti-cheat system, Javelin, isn’t a “silver bullet” solution, and the truth is, there simply isn’t an anti-cheat system today that truly works as intended.
I’d compare the situation to a summer evening where a man stands trying to swat mosquitoes with his bare hands. No matter how many he manages to kill, there are always more coming. That’s pretty much the reality of today’s FPS games – an endless fight against cheaters.
In the end, it comes down to how you choose to deal with it:
Either you accept the situation and put up with these “bloodsuckers” only play with people you know, stick to matches against bots or just stop playing online FPS games altogether.
