Here's something else I noticed today. I joined a jj2 server more early today when someone first joined a server under the name Domo (he is player #2) and he started to cheat using ears to fly all around the level with JJNOWALL on. Guess what happened next. Suddenly lots of nonames started to appear in the player list, someone edited the server count (it was 10 before but now it's 60) and some player score also got edited. But that's not all! As you can see the "Domo" guy was able to make theWINNER say stuff he didn't (probably packet editing sending again). I'm telling you there are multiple people who can do it!

Sorry but this is the only screenshot I got.

I'm gonna report more of this as soon as I see it.
