That's one of their videos. Depending who's talking it actually does sound spot on.
I've even heard one of them in-game myself and it's VERY close if not perfect at times. 

They have a discord but they keep the voice instructions hidden so people don't snag it and simply leave. 
They demand you stick around, earn their trust, and participate in their events.
If they happen to like and accept you? 
THEN you'll get full access to their discord server and be able to see the voice instructions and such to re-create it.
