Yes people do just call good players hackers but I only say people hack when their player is bugging out due to too many hacks on at one time. I really do think though that the hackers should be perm banned and have to make a ban appeal if they really want to be unbanned.
Your claiming that a glitch that can produce an error in a players approximate location, from VANILLA Minecraft, is the result of "have too many hacks on at one time."? You do realize that having a ping of 10 means your going to beat anyone with a ping higher than yours... Your game is updated within a hundredth of a second, but their game is updated, in most cases, every .2 seconds, as most peoples ping can exceed 200. The result is that the low ping player is playing in real time against an opponent who is attacking the position they were in .2 seconds ago... Perhaps that will help with your claims of hacking because you lag and they don't...
Also, if they are, let's say occupied in a bow fight, and you sneak up from behind by walking, and they just turn around and shoot you too. That's not hacking either, that's just a carefully adjusted sounds setup in which they put an emphasis on player noises... Your footsteps could very well sound like thunder claps to them XD
Let's say you think you've cornered some guy and you jump in for the kill, your doing you best to strafe, and go for the crits, but despite your best efforts, your taking hit for hit and lose becuase some part of their gear was better. That is likely to be the result of a high DPI, or sensitivity, mouse combined with quick reflexes and PvP experience; contrary to popular beleif, if they win the fight with 1 HP left, they probably weren't hacking
