ban for no reason

So I was playing Hide and seek and basically, Im playing as a leaf, and then suddenly I got a message from the watcher that I got banned because I have a mod installed but I don't even use mods and I'm playing the game fairly, please notice this appeal cause I'm playing the game with no hacks.

I was banished without reason my nick and JoaoNegao007 and I wanted to know why I was banned
