First and foremost, be careful about putting usernames in your posts, as that could construed as "Name and Shame." Why they call it that, I don't know, as anyone willing to cheat in a video game for the sake of having a high score clearly doesn't experience shame, but I digress.
Second, as someone who makes a career in the cyber-security industry , which includes consulting for the gaming industry, I can tell you that preventing the hacks/cheats is a reactive business. There is only so much a company can do that fits into the scheme of keeping the game playable for the masses vs. unhackable. And, as long as there are rat-bags out there willing to pay for cheats (remember your economics classes...supply and demand), there will be a market for hackers to continue to work on developing exploits and hacks. Keeping up with a group of talented hackers who devote their time to exploits is a tough ROI, so it remains a reactive process. Hackers develop hacks, software develops detection/patch, hackers develop new hacks, and so on.
I have developed the following system for evaluating potential foul play:
1. If a player is getting above a +4 K/D ratio, I take note. I play mainly the fast, high death games like BLAST, CARGO and Turning Point; achieving a +4 K/D seems like something only the Olympiad level player should do
2. I use the Shadow Play feature of the NVIDIA suite and have it set to capture the last five minutes of play with a set of hot keys so I can go back and review when I keep getting killed by the same player
3. I look at the star cards of the player, mainly to check for Scan Pulse (amounts to a bona fide in-game wall hack)
4. I look for unlikely shooting match ups (the shotgun thingy killing me from across the hanger, or an E-11 killing me from behind the dunes on Turning Point when I can barely see a spec of the player.
5. Does the player seem to have infallible accuracy?
etc.
There are other factors as well, but before I over-react, I try to evaluate objectively and if all these tests fail, I report. I also immediately drop out of any game where I suspect someone might be cheating.
I think there is a great set of unfortunate circumstances that make the game feel very rife with cheating/hacking when it is probably a mixture of half cheating and half bugs that EA probably is in the process of fixing but doesn't want to publicly acknowledge prior to the Christmas sale season.
Anyway, my 2 cents. Actually, my 0 cents since I don't get paid and am just sharing an opinion.
