It's no surprise.
So many online games have been hacked or compromised in so many ways, the automatic response by these little cretins is the auto-cheat!-reflex. Aimbots, shade accounts, actual cheats and work-arounds are legion in many games. It's a simple fact of online gaming. People with so little self- confidence and respect need to do ANYTHING they can to increase their self worth.
It can't be that they or their target have a under performing rig, or one that is so chock full of spyware, viruses, and various 60-odd unneeded threads running in the background. Society has taught them that everything is somebody else's fault, not their own.
It can't be that they upped a fully fueled Pony to defend their base at low altitude. Or they've no ACM skills. Or no situational awareness. Or no fire discipline or gunner skills. Or no patience. Or any clue.
Get a squeaker like this: step one is to make an attempt to edumacate dem. If on the other side, see you cannot enlist someone locally on their side to address the issue. Give them an honest, fair, civil response.
If step one does not work, then it's your choice: ignore, squelch, make fun of them, taunt them till their little head explodes, mercilessly hunt them down all night. To each his own. But first, try to inform and educate. I'm all for online Darwinism.
