They usually turn off their hacks if you do.
Nope.
No hackers "turn off" their hacks, they might ease up a bit on the killing spree, but hackers won't stop hacking until banned.
Hackers are there to annoy you, to ruin your experience, most likely because they can't get any satisfaction of playing a game fairly.
If you shout at them in anger, they've succeeded.
If you see someone clearly hacking, report the profile via Battlelog, and if possible, try to contact admin of the server to see if the hacker can be banned from the server.
Do note though!
Just because someone has 60-0 score (or 180-0) doesn't mean they're hacking. They can either be camping with a sniper, using a tank/other vehicle with someone using engineer to cover them, or using any other tactics and strategy giving them such scores.
In fact, i've seen plenty people those time's i've been playing Metro that has 150-0 +++ score. Neither of them we're hacking.
Sure, they used M320's, grenades and such, but that's a part of the game.
Just my opinion on the matter though.
