Banned For Apparently Hacking???

Hey Mods and Admins,
Ingame name: matyou888
Ingame name of the one who banned you: I am not sure
Server you were banned on: Factions (squadcraft.net)
Reason for ban: Hacking??
Ban length: Do not know
Why you think you were banned: I have no idea
Proof: I have no hacks or clients installed
Any extra things you want to add:
As I logged on to squadcraft today and went on to the factions server, I was in my home like normal. As I typed /spawn I teleported and got banned. It says I have been banned, the ban hammer has spoken. I would like to be unbanned please as this is unfair and did nothing wrong.
Many thanks
Matt
P.S I have some screenshots of people fly hacking on skywars
