I probably shouldn't antagonize the admin position on this issue because I'm a nobody around here, but I have to basically agree with those against the blanket no-spawncamping rule. I personally think a no llama rule is plenty. Spawncamping of the worst sort described in this topic is clearly llama behavior, like tking and parasiting your teammates. If a player is a llama, he's probably showing it in more ways than just killing some people in the spawn. If this llama is being so annoying as to deserve kick/ban, do it. But to blanket remove such a basic part of NS gameplay because it isn't "fun" to be on the recieving end seems excessive.
I used to admin on a CS server with a sizable community like this one. We were a ff server, and so had many of the same llama problems you're trying to deal with here. For us, the answer was easy. We banned llamas. Lots of them. Our ban list had over 13000 wonids. But the game play was always good, and after we banned them all, llamas were rare.
Now, I admit a couple of important points here:
1) we were a "pub", but we catered to cal-clanners. if you weren't cal-o quality or better, you would have had no fun at our server. And we liked it that way.
2) CS is a very simplistic game compared to NS. this makes llamas easier to spot and ban, and evades some of the complicated issues brought up in this topic.
Well, enough antagonizing admins, I'm outa here to go play before you decide to apply the above llama ban concepts to me...
