I read the OP and instantly regretted it.
I hope you realize, you find these people EVERYWHERE, not just god damned Tezuni's server.
Also, the actions of the players does not directly effect the server, nor do the admins, but the host. That should be where the quality of the server is judged.
As an admin on Tezuni's, I can freely admit that yeah, some people are really loving annoying and there are times where we can't do anything about it. Get a clint-sided mute script, it works wonders.
What really boggles my mind most though, is how this isn't even really a drama of Tezuni's, it's a drama on the players, who happen to play Blockland PERIOD, but it's focused on Tezuni's server... So I guess hypothetically people just stop being human and take on some other personality on the server. Pretty trippy.
