I saw a guy using 5 account in a tourney he using he's account 5 account! i got proof i will attach it

You need to post it as you make the thread.

So we do not need to ask for it.

I was there too. So here's a proof.

how do you know that he was using 5 accounts?

as i entered the room. androidex was already there. Its not actually 5 accounts. he used one account and opened 5 toribash app and entered the 5 same accounts in one room which is the tourney8.

he will banned ?

most probably until mods will see this thread.
Im not sure if this should be posted here.

As we normal users can't help you with this, you don't need to post something like this here. Easy as that.
So, next time try contacting a SuperModerator or a GameMaster.
