Not at all, i didn't know hacks before playing Minecraft, and since minecraft is jar based i had to edit manually the folders, but i play Minecraft since three years, League of Legends since two (where there are no hacks) and S4 League, where there's an anticheat too, never cheated before Minecraft, except on singleplayer games with ye olde Simcity 4, The Sims, and various FPSes, RTSes, etcetera.
I have not a single hack for this game, especially cause i didn't want to get banned, and the bypass did get me banned anyway.
Edited:
I don't know, the file has been there since i downloaded the game the first time.
Why are you still posting? What do you think you can prove with shoddy evidence and words? It's not going to get your ban reversed, why are you still trying?
