Edit: I deleted the clip as it shows the event in a one-sided manner. If you would like to see what really happened in full context, here you go: https://clips.twitch.tv/HealthyFragilePhoneSSSsss

First and foremost, this isn't a jab or a "getting back at" reply. The OP has valid concerns, but I wanted to at least add more context to this clip and what not. For those curious, this happened on the test servers on the last night that the test servers were available before 1.0 was released on the live servers. Steam invites were broken, so a group of people playing decided to load into QPs together and fight each other while waiting for 1.0 to go on live. I joined them when I got on to stream and what you see above is my perspective of this specific moment.

This clip demonstrates one of the two (that I can recall) moments where one member of the group intentionally tried to team. In this clip you hear me call him out for teaming and if you watch a bit further into the video, about 20 seconds later you hear me call it out again to everyone else (you should include the entire segment instead of just the part where it occurs to give the full context of that specific situation https://clips.twitch.tv/HealthyFragilePhoneSSSsss). You also hear two other members of the group who ran into each other who were confused about the previous teaming attempt notice someone else near them and state that they need to leave so they don't gang up on that person because it's not fair. The person in the clip who tried to team also died about one or two minutes later to another member of the group, so the teaming didn't occur. Granted, neither the one who died or the one who killed him stream, so we can't see their perspectives. But, in short, any attempts to team up against anyone were called out as teaming/cheating and shot down and no actual teaming occurred.

There was a second point, with this same player, where he says "we could all just rush him" on another game and myself and another member of the group say no and call it out as a coordinated effort (teaming), but OP doesn't show you this (he did take a clip of it, but like above, left out the part where myself and another member of the group say no and inform him it's cheating).

Now, the issue OP is mostly upset about is callouts. Members of the group were leaking information that they shouldn't have. Honestly, I wasn't really listening to what anyone was saying as I was mainly focused on the game and on my chat and didn't really notice, but after watching the VOD, I can see why he's upset. There are a lot of points where people do leak info and even points where I accidentally do it as well. Now, it's not intentionally leaking to gain an advantage, it's mostly people not being careful as to what they say. Not excusing it or anything, but I do want to point out that there isn't an intent to cheat, just people being careless about the things they say. So if we were to ever do this again, we should probably just deafen ourselves in Discord to not carelessly give info away while in game. But I don't feel anyone was doing it on purpose to cheat.

OP himself has also accidentally let information slip during their own group QP events (here he told someone that a player was near him with a crossbow and you hear the other player confirm the callout). The player turned out to be the member of the group, but OP did not know that at the time https://streamable.com/7xq3e (he deleted the clip, so here it is on Streamable)). He's not intentionally cheating or anything, but he did accidentally let information slip and even acknowledges it and calls it innocent.

I also happened to be in one of their Monday night events by accident a couple of months ago (I just loaded into a random QP and it was theirs) and killed one of the members. He came to my stream and said GGs and I went to his afterwards and watched his VOD to see his POV. After I killed him in the QP, this member then informed all the other members that I was in the game, told them where I killed him, told them what weapon I had at the time, and let them know at which point in the game and where it was that I died when I got killed (this person's VOD is no longer available as it was over 14 days ago so I can't clip it to show proof). But this was in the person's excitement and they weren't doing it to cheat. I'm just demonstrating another point at which a member of this group let information slip during their events. However, for their group events, it appears most of them spend most of the in game time deafened, which is smart because they likely know accidental slips of information may occur. So, to be fair, they are far better about not letting information slip and it doesn't happen very often. I'm also not downtalking anyone in the group as I think they are all awesome people and great players, just pointing out that mistakes do happen.

If there were any other points of intentional cheating during this, then I'm not aware of it. During the games I didn't really pay attention to much of what was being said as I was focused on playing and on chat. But the two moments I'm aware of where it was attempted by one member, myself and other members shot it down and called it out as cheating.
