Hello, and thank you for your request.
I reviewed the demo and my opinion on this is that at the moment when you recorded the demo there where no more than 6 players (at least active) on the server, players that have agreed upon having some fun, without ruining the gameplay. At the moment when you stopped the demo, the ct's where shooting at a prop, trying to get to the last zombie, also one ct has killed a zombie by knifing it.
Again, players have agreed on having fun until others join the game. I will not issue any kind of warnings here, as this did not lead to any disturbances to the gameplay.
