Evidence----------: greenlee5 and Th4t_0ne_Guy got into our new base (our faction is TeamNova) without claiming it and we claimed it. They also you jump and speed hacks. I was unfortunately not able to take a screenshot without dying. Me (IGN: ts4437), seano13, silverlugia1000, RickyAFlores, and chedd knows they're hacking.
Our faction is just being bombarded by hackers! ):

==============
Additional Information:
seano got killed 10 times, each time in one shot by greenlee5's diamond sword. (not enchanted)
Seano13, RickyAFlores, SilverLugia, Chedd, and me also saw Th4t_0ne_Guy use a fly hack
they also have x-ray because silverlugia1000 made a secret chest and they somehow were able to find it and grief it without claiming.
I couldn't get a screenshot but I will try later if I can
===============================================

ive seen both of them fly too. i tried to get a screenshot but they have speedhack and i cant get a clear shot because they chase me away.

Please get evidence for me to look into situation.
