My suggestion would be to IP-ban hackers if that isn't happening already. 70% of the hackers on cubecraft are people who get a free alt from the internet and then just go on another alt when banned. So they keep coming back. So in my opinion it would be best to IP-ban these hackers. I also wouldn't understand why not IP ban hackers? It might be possible to get around an IP ban by changing your IP or something, but it will decrease the amount of 70% back down to like 40% or lower for sure... Also why would you have mercy with hackers and not IP ban them? It's a clear rule and everyone knows you're not allowed to hack, these kind of people don't deserve a second chance... If they have a brother or sister playing on their IP, it's their fault for hacking and getting themselves IP banned in the first place...
