that's totally lame of them. it's just a freakin' game. these people at vmk need to lighten up. seriously. i never go on anymore because i'm always afraid of saying something wrong and them yelling at me. what's the point of being able to talk in vmk anyway? you have no dictionary to use and you can't say anything about anything because you'll get warned and/or banned.
i'm sorry this happened to you.
maybe you should ask them to see the chat log?
they could be lying, you know. (i've been dealing with liars in a situation that happened to someone close to me recently, said that things happened that didn't and they threatened to sue, even paid a lawyer to send a threatening letter!)
