Flying and invisible hackers

[Laura_Aria]

Today I was playing Survival games and I saw a hacker.When the game started he got full diamond armor straight away.And as far as I know that's not a kit.After that I saw him flying in the air.He even said he was a hacker himself.His IGN is LuanPvPGamerFD.I hope you can do something with this hacker.And I found another hacker.He was killing many people.He was invisible.I'm sure it was not a glitch because I saw him kill some people and those people didn't even hit him back.And when I saw the invisible person killing people including me it says his IGN was Action23.So please do something with these hackers.Thank you
