Sorry, but you clearly have little idea of what a normal player and what a lagger is. I will tell you straight up that every single thing on your Hacker list can be accomplished without 3rd party software (hacks.)
I am "defending" JEEFERSON... simply because I know he isn't a hacker, he's a lagger (and might not be lagging intenionally). On your insulting part, let me tell you, if we banned every person in the game who insulted people we would be left with 99% of guests and 1% actual players. It's not even against the rules, unless you say something like "you sack of horseshit, die in a fire", it says right there in the rules that "noob" is perfectly ok to say.
Anyways I'll expand on your hacker part.
Teleportation - that comes from lagging, you start at one place, they think they are moving, but since they lag they stay there, then they go back to normal. It's lag jumping basically.
Immortality - lots of ways this can happen. Undead corpse glitch, good players who want to be immortal can basically be immortal if they run to base 24/7, health bar glitch can look like ur doing 0 dmg when you are (and they keep full hp bar). Infinity bombs is a known glitch, infinite statistics - i assume ur saying infinite health? that's a glitch too as I said. Intangibility - undead glitch, exit the map, out of map glitch, all characters unlocked, not even lag or glitch, i have all characters, I've just been playing regularily for a while and have unlocked all characters using z-cash. I am only g2, and im sure that g5s will easily have all characters and more.
FFT is not a normal game. There are tons of bugs, and lagging is an ADVANTAGE sometimes. I defend JEEFERSON, only because I am sure that he IS NOT a hacker, and only a lagger/bugger. Trust me on the bugs/lag part - I have either personally done them in an empty room, been told i've done them through lag, or have seen a friend do it and show me how.
Your closing line sounds ironic to me. I hope this helps you differentiate the two types.
