I generally agree with Micah's analysis of how and why Krems exists. As what is its causes.
A bit of fun now and then is not a problem, but there is a limit somewhere, and I suspect that limit was reached a long time ago.
As others said, we are a very small community right now, and we have to respect each other. Krems is feeding on others trying to play the game how its meant to be played, and if they leave, Krems might as well be alone in an otherwise empty server.
If their behaviour results in delaying, their own team loosing or general griefing the choices should be simple.
Start behaving, leave the server for an empty one or get a ban.
Again, shouldn't be some Nazi style execution of Krems players or others. As long as its fun its fun, but they need to be let know when its not anymore and when enough is enough, and what the consequence of not taking the hint is.
