Fortnite Banned for no reason.

I'm guessing you're banned for alternative accounts - Or even logging into accounts that have been hacking, Meaning you will have been IP Banned - Maybe change your IP and try to log into an old account or New account see if its a HWID ban.

i'm agree the account can not be banned without any reason....

Most likely, the cheats banned you. You are just a cheater.

I got banned to for playing in my Iphone whlie I was in netherland

Yea, as said above if you contact epic games you might be able to make a ban report and reroll your acount.

The reason is because you've been playing with bad stuff... So, they banned you
