Righty-ho. My friend and I were banned from the Texas Ten Men server earlier today because we were apparently hacking by killing people easily with the HMG turrets during a Crash Site match on Skyline. I don't think I need to tell you that neither of us were hacking and the entire opposite team were far too stupid to circle around and kill us before charging blindly into the various crash locations.
Before you cry and bich over someone hacking, I advise you all to look if the player has any deaths/assists, if they're flying about, what weapon they're using and if you're actually playing well at all. It'll save you looking like a twat when you ban someone for basically being better than you.
tl;dr- stop crying hacker or unfair at everything, use your brain+tactics, deal with it.
