I have removed the ban from you account, had it not been for your high latency (300ms>), you may not have been false flagged.
For previous false bans I have been able to find a reason for such however I am not too sure if I can confirm this was false. Please check your client for any mods that act as a "trigger bot" and increase the size of an entity's hitbox as you set off this check over 30 times (leading to your ban).
