Hello!
"do not know if they were communicating / giving intel over that discord channel or not since I tabbed out pretty late, but it does seem that there are probably 2 of the raiders in that channel (Both on full-mute on the screenshots)."
We were not communicating via discord to share anything about this raid. (we were "muted") The only reason why the stream was there for a friend to see whats going on while he was actually playing a different game at that moment and he was simply bored. (as you said he was not part of it) The actual communication was done via radio's which we handed out prior to that event.
Jester was also not part of the raid nor even watching the stream, due to him being away, and cooking in the meanwhile.
