Hackers are a problem, I agree. Your not alone. But you have to remember, were humans, were not perfect nor are our creations. There will never be a way to completely get rid of hackers, as sad and pessimistic as it seems they'll keep finding a way. And I saw someone say this already but I'll be adding it in here as well. No one is making you play here. Even if you went to other servers, you know what you most likely are to find? There are hackers EVERYWHERE. I also don't understand what you want to accomplish with this thread, the staff know its a problem, quite frankly they are the ones who have to ban them; they know them probably better than players. I digress though, good luck with whatever you do.
OOO I forgot something. Its probably not as easy as it seems to make a plug in or script like what your describing. Actions speak louder than words.
