1. Your ingame name: Enderkiller1327

4. Evidence/screenshots:

 

Finally some evidence

 

But you seem to be hacking too. Too left corner

 

@Pile_of_Butts please take a look at this it seems to me that both players are hacking but I may be wrong... Thanks!<3

 

Those aren't hacks, 1 is health mod, tells me how much health they have, then the other one is the armor and potions mod, tells you the durability of your armor, all mods, no hacked client,
sadly, i'm not stupid enough to report myself

 

Thanks.
