Either your are trolling, or are misinformed. The hacks are client side, not server side. There is no way the server can tell the difference, unless the client sends something back to the server. and for example, no debuffs, the server send the client the message to be blinded, and you become blinded, but if you set up the client so that it doesn't blind you, it doesn't know, because either way, the client doesn't have to send a message back to the server saying that it is blinded. Games like this that are mostly client sided, are easier to hack without being detected. If the whole game was mostly server sided, and the client had to send all the actions to the server, it would be hard to hack (and it would be extremely difficult to host all the players on the game).
Edit: So, you pretty much cant be banned

Unless you are seen using aim-bot or something by a mod. There is no way to see if the code is edited though. The only reason the item hack people got banned, is because the client has to send a message to the server saying that they bought something, but for something as simple as aiming, or debuffs, they have no way of telling, unless they see it happening. I have never seen anyone banned for hacking (other than item hack). Hope this helped!
