Dear,
The AntiCheat detects hacks from players suspicious movements and this can be recreated if a player has a very laggy or unstable internet connection. You must have had bad wifi and started to glitch out and the AntiCheat must have thought you were hacking and banned you for it. If it happens, then you can contact a Jr.Mod or above via Discord or Forums for an unban.
Regards,
JaySN
