Listen up fucker, I am pissed off by people like you. "Omg there's a problem why don't I blame it on fucking dan". Listen up, grow the fuck up and stop being a little bitch. You didn't even use fucking in a worthy context, which leads me to know that you're a 9-12 year old.
Woah! Calm down people, no need to get mad over nothing. As mk1alfie said, it's to prevent hackers. If you don't like it, nobody is forcing you to play on the server. Also, I highly recommend not using such language on the forums, Dan is serous now so you will get a ban or mute. Your choice though.
