I enjoy the gcftw server. Most of the time.
No rushing? Sure, great rule.
No swearing? Well fine, why not. I can handle not raging at the newer players.
But getting kicked because Maestro.gc thinks the letter 'E' is inappropriate as a name, and is used as slang for a drug? Why, it's absurd. E is a shorthand nickname for Everett, my last name.
I totally get why you couldn't have a name like 'Pornlvr420'. But christ, EVERY letter in the alphabet can be slang for a drug, and just about any random word you can think of.(1)
In a game where zombie heads are constantly rolling around, blood spurts from every angle, and even the characters have their voice-over swears, it's completely ridiculous to think a letter can make someone so upset.
