Well, I know from when i had admin rights still that there's always a way to get the chat history from a game back.
IF... you never have said it Thunder, then i guess its the admin that needs to proof that with a screenshot of the chat history from that day because if you are being pointed out that you did then i guess the admin needs to proof it also just like any other. If other people call someone a hacker, it needs video proof, when an admin says you called someone hacker, then how easy would it be to get the chat's history and show it here and proof you said it.
My guess is that, you are innocent until it is showed by the admin that you said it. And if they can't proof it, well then that would be really really stupid to type in this tread anyways.
And until that time, you can ALL suck my hairy balls for taking my time needing to write this while i could have shot someone in game.
Woomp... there it is!!!
