Fireteam Auto win Glitch?

Well, I was playing and I came across this room called Fireteam Auto Win Glitch so I joined and turns out it was true. I got about 40 masks on extreme. I tried to record it but my camtasia studios didn't work and I tried fraps and it didn't record the whole thing and right when I got it to work he left. He was there for a good hour or two.
Anyone know about this glitch?

I just see him AFK in there and he says something like

Wow that is super cool. I need to find this crap out.
