It's not different. Trust me on that one. It's same because they are basically ban evading and you guys are allowing that to happen.
I was an admin and server mod on a server but it was a different game. Funnily enough - these morons on the game where I was an admin and server mod they literally had temporary and for hackers. From 3 to 6 month bans.
You guys are basically letting them to ban evade. They can repeat the same thing all over again. Cleaning out their bases won't stop them to continue hacking on different accounts. You're aware that morons like that are stupid enough to waste time and hack people's MC accounts.
Even an IP ban won't stop them unless they have a static IP, you know, it doesn't change every 24 hours or when you restart the router your IP changes.
We both have different experiences in this kind of thing hence different opinions. All I'm saying is that Crafty and others should take this into consideration and discuss about it.
