Well, basically. I was playing on my server and a group of 3 people joined. I had checked their profiles due to their character names and steam names. All private profiles so I got a little suspicious. I little later on, I caught "desu!!11" speed hacking and banned him. This is what happened. I'm also guessing that "Daenerys Johnson" is a forum member. Now, this could be a joke, but while they were on my server was lagging quite a bit. Should I be worried?
