Jailbreak is no harder to admin than any other server, it just takes different methods/strategies than over servers to manage properly. Decreasing the slots by 4 people will do absolutely nothing to stop with people talking over each other. Even when we had 24 slots people would talk over each other like this all of the time.
If Ts are getting shot because of confusion than that is the fault of the CT and his team because they are not being clear. This is why there is a conflicting order rule on the server and an explanation to what conflicting orders are. Jailbreak is about the CTs working together to control the Ts and if they can't do that then they are only hurting themselves.
As for the situation frost was if it was needed he could of muted the entire server to tell the one person why they were slain. However, im assuming he gave them warnings before hand about it and it really isn't necessary for him to mute the entire server to tell one person why they were killed. Also, there is text chat that he used in the video as well. I think he had control over the situation.
