Me and my friend Rosen we're playing a friends only game and since I had school work, I went away for a bit. Rosen was playing by himself while my idle bot is there messing around and someone joins. There was NO invites from him to either of us so once I get back, the chat is up so I take a look at it, and read it.
The guy (Who none of us know) starts a vote to kick Rosen when I am away.
For some reason, Rosen feels annoyed and calls him a name.
The person replies and says that an -name- can't use a mouse.
The person leaves and I come back later, After hiding in the safehouse when I get the pictures, I then start a vote to go back to the lobby.
It turns out it was really friends only.
We had no cheats or any mods on, so I have no idea how they got into the game.http://imgur.com/e191K
There is the picture for proof of him joining the game and Rosen calling him a name.
Rosen doesn't think he's a hacker though :/
I just wanted to either get him warned or banned for a bit, and maybe warn other players about him.
I don't play public games on L4D so I don't know how he was able to join.
