I agree with both of the above posts.
Like Kit said, the maps were not designed to accommodate the amount of traffic our servers receive, so no matter what, there will inevitably be some spawn killing/camping. We advise all of our admins to politely ask the offending player(s) to stop spawn camping. After having been given a polite verbal warning, if the player has not stopped their transgressions, our admins are then instructed to warn that player with the b3 bot. If the guest does not stop spawn camping, we ask that the admin warn them a second time and then a kick if the guest doesn't listen at all.
Now, we keep a tally on the amount of warnings all of our guests receive and if their number gets too high, we start taking harsher action. We start off with short temp bans and it goes up the line to a permanent ban. We also ask that our guests point out any rule breakers while in server, sometimes when you're playing you get caught up in the game and you don't always see everything, so please feel free to ask any admin in game to watch a player if you feel they are breaking the rules. You can also always record a demo and post it here and we will then take action from there.
We greatly appreciate your feedback and I hope you understand that we are doing our very best to make our servers a fun, clean place for our guests to play.
