Very strong privileges for VIPs/admins: extra HP, extra damage, extra movement speed, reduced damage taken (basically even more extra HP), a ton of heals, special weapons with reduced spread.
And the "top" players (as the server population calls them: "pros") in addition to VIP perks paid extra to buy even stronger guns with almost no spread and extra damage, infinite ammo (no reload), double jumps, and a billion heals that they can use instantly, without animation, on the move.
So the "best" players just run +w around the map holding down the fire button and kill everyone.
And if you, God forbid, kill one of these "pros," you get banned for cheating.
Furthermore, if a real cheater is playing, the 5 admins currently on the server just don't care about him – the main thing is not to kill the "top" players.
The head admin also doesn't give a damn about anything: regular admins don't ban real cheaters? Whatever (he literally wrote that he knows about it but won't do anything). And if the "best pro player on the server with a billion privileges" bans a regular player who keeps killing him because the "best pro player on the server with a billion privileges" can't actually play, the head admin also doesn't care – he who pays the piper calls the tune.
So there.
