Hacking in the ranked FG: Courageous Assault

So someone managed to sneak into my guild and blatantly cheated their way in the ranked FG and I had no idea until someone PMed me. Here's proof:

Here is my FG score if it matters: http://i.imgur.com/3V9tRzM.png

I apologize to all the guilds that are legitimately at the top ranks as I am currently talking to their live support and it doesn't look like they can figure it out straight away. I'm hoping our guild does not steal away their rewards.

It also looks like our entire guild may be punished for it unfortunately since we were rank 74 this morning, and I'm not entirely sure which of our new recruits are using third party cheats.

EDIT: Special thanks to u/Kainoa25 I kicked the very last person I recruited. Rankings have reset to what it should be: http://i.imgur.com/9k8pKHI.png. I have reported the user afterwards through live support, and hopefully he/she won't cause other guilds to suffer the same humiliation as we did.
